**HOW DOES THE TENNISDC TOURNEY WORK?** **EVERY MATCH COUNTS** **Tennis Tourney Basic Concept** Our tourneys are a single elimination format with a consolation bracket. Meaning you are guaranteed at least 2 match-ups. This tourney format will not be played at a single location over a weekend instead players are given 7 to 10 days to play each round's match. **Expectations - Updated 3/30/21** Our tourneys will be mixed gender unless we have particularly strong female enrollment in a city. The tourneys will be singles based until we receive enough response to open it up for doubles. This is the most competitive format we are offering. We now won't guarantee leveling in Tourney's. If we have enough players we will create two draws based upon perceived level. We strongly advise low level players NOT to join the format as there will be higher level players in the draw. **Our Guarantee** We need at least 6 players to make a tourney bracket. If we can NOT reach this criteria we'll send you an email offering a refund or we'll enroll you into the next tourney with your entry fee. Our hope is to run multiple skill level brackets for multiple draws. **The 7-day money back guarantee expires as soon as the tourney starts.** Tourneys will NOT allow for late enrollment. Players will be entered into the tourney that associates with their TLN's Player Rating. If a **NEW** player (Someone whose played less than 6 matches with our service) wants to join the tourney they will **agree to be placed** in the tourneys highest bracket. (This is admin's discretion) The League reserves the right to remove a player from a bracket if it is determined by match results that said player has more likely underrated their playing ability. **Your Schedule and Availability** We give first round opponents two weekends to play the first match and then each following round will have a full week to play the match. Players need to be available to play for at least the first 3 weeks after kickoff. Players with 1-week work trips or week long vacations during the first 3 weeks shouldn't participate in the tourney. **Seedings** The TennisDC staff will seed 25% of the participants based veteran status (Most number of matches played in their career) with the program. If we have 8 players enrolled we'll seed the top 2 players, 16 players the top 4 players. The rest of the players will be randomly entered into the draw. **Consolation Bracket** We will run a consolation bracket for the players who lost their first match. Seedings for the consolation bracket will be randomly selected by the TennisDC staff. The winner of the consolation bracket will receive at least a $25 Gift Card. Matches need to be played to crown a consolation bracket winner. **Where to Play?** Because the seeding of the tourney is mainly randomize the higher seed will NOT have home court preference. The league strongly suggests you meet half-way to cut the commute in half for both players. We provide an extensive list of [tennis courts](https://www.tennisdc.com/TennisCourts) that have user submitted ratings. If two players need guidance they can certainly email our staff for suggestions. Playing Format The preferred playing format for tourneys should be 2 sets with a 3rd set tie-breaker or 2 out of 3 sets. If the two players can't agree the default format will be the 2 sets with a 3rd set tie-breaker. In NYC we will accept 10 game pro set results mainly due to court availability. **Target Audience** This will be our most competitive format. The target audience is for the player who are good sports and love to play competitive matches. Prize Pool Starting in 2022 all Tourney's will now have a Cash Reward option. 70% of the proceeds will be awarded back to the Winner, Finalist and Consolation Bracket Winner. The players can choose a Paypal payment and/or items from the Prize Pool at the nominal value of $25 each. Prize Pool is a choice of a combination of Free Seasons, $25 Gift Cards, Items from the Swag Page or donations to Cancer Research Institute or Boston Food Bank. All tourney champions will be receive an entry into the End of the Year National Tournaments at the champions discounted rate. Cost to Participate First fifteen players will pay only $29.95. Following players will pay $34.95. A low cost way to play competitive tennis. **[JOIN TODAY](https://www.tennisdc.com/join)** So [Join Page](https://www.tennisdc.com/join) and we'd be happy to get you enrolled into the next tournament. **Finer Details** \* If a player doesn't respond to their opponent for the main bracket match they will NOT be placed into the consolation bracket unless we hear from the player. \* A match needs to be played in the consolation bracket for a gift card to be distributed. \* A player who doesn't give a reasonable availability (Most matches are played evenings and weekends in this program) to play the match within the deadline window will be at risk of defaulting the match.

What if the best product requirement was a working prototype? Amazon built an empire on one principle: start with the customer and work backwards. Identify the durable need. Resist building until you know what you're solving - and for whom. Vibe coding doesn't abandon that discipline. It supercharges it. Join us for an in-depth discussion on how natural language becomes structured specs, specs become architecture, and architecture becomes working software - in real time, in the room, on your machine.

This event is session 12 of 12!** **This event is free but has very limited seating and we are limited to the first 50 to RSVP! Join us and become a founding member of this amazing community!** *(it is ok to attend even if you missed previous sessions. Each session has stand alone topics. You can also attend other near by locations to get caught up on sessions that you have missed.)* **Very limited seating. In-person only.** **Make sure to RSVP today to reserve your spot.** **When: April 23, 2026 @ 5:45pm - 8:30pm EST** **Where: Twinbrook Library** **202 Meadow Hall Dr, Rockville, MD 20851** The Cash-Flow Breakfast Club is NOT just a meet up. It’s the most unique Real Estate Investor Community of Mentors, Coaches & Masterminds. A community of growth oriented, abundance mindset, go-giver individuals with a BARE MINIMUM commitment to become financially free through real estate investing. We focus on providing education and building networks to help every member solve their cash-flow freedom equation, so they can have the time-freedom needed to follow their passions, make a lasting impact and even change the world! The unique format of this event, which consists of high-level education, gamified networking, mastermind breakout sessions, case studies, group deal analysis, market deep dives, and peer-to-peer coaching facilitation makes this the most impactful local real estate investor group a real estate investor can be a part of. The foundation of the group is built around the belief that everyone in the room has the potential to change the world… however most of us never have the time, energy or financial situation to even dare to dream big enough. Most of us have passions that will never be followed, amazing businesses or ideas that will never be pursued… unless we can solve the Cash-Flow Freedom Equation, which ultimately leads to Time-Freedom. Once that happens it is usually much easier for us to think bigger, dream bigger, be bigger. · 🤯 Learn more about the Cash-Flow Breakfast Club [HERE](https://cashflowbreakfastclub.com/) · 🥇 Get in the VIP List to be notified about the next event in your area [HERE](https://the.cashflowbreakfastclub.com/VIP) · 🤙🏼 Learn more about Launching your own Cash-Flow Breakfast Club Location [HERE](https://cashflowbreakfastclub.com/launch-your-own-club/) · 🤝🏼 Learn more about becoming an Affiliate-Sponsor at one of our club locations [HERE](https://cashflowbreakfastclub.com/affiliate-sponsors/) · 📷 View photos and videos of some of our recent events [HERE](https://cashflowbreakfastclub.com/about-the-cash-flow-breakfast-club/) · 😎 Looking to represent?

This session introduces Squad: an open-source framework for multi-agent orchestration that lets you define teams of AI agents with specific roles, responsibilities, and expertise. We'll progress from Copilot basics to the Copilot CLI, explore how Agents add autonomy, and see how Instructions and Skills let you customize agent behavior. Then, the climax: a live demo where a Squad team of 3 agents (Lead, Developer, Tester) stands up and builds a working application in real-time, showcasing true multi-agent collaboration. Whether you're new to AI or exploring how to scale your use of Copilot, this session will show you what's possible when agents work as a team. **YouTube Link** TBD

This is an in-person meeting. At this meeting you will get answers to depression and anxiety. Find out the source of them and how to get rid of them. Did you know that unwanted emotions like anxiety, depression, unhappiness, loneliness, hopelessness, anger, fear, or feelings of irritation don’t just fall on you for no reason. They are not random occurrences that simply happen to people's minds. They are definitely not due to a chemical imbalance in your brain from some nebulous chemical reaction "by chance". Your negative emotions are the symptoms of the painful experiences that you have which are not healed, and which are still affecting you. The effects of these painful experiences are exacerbated by the pressures or difficulties of the other problems in your life. Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life. Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there. This group is created by the Hubbard Dianetics Foundation of Central Ohio and Church of Scientology of Central Ohio.
