Please join us for an evening of all things Umbraco - the latest news, community chat, and a talk or two! For 2026, we will be running both in-person and virtual meetups, alternating every month. For those who can't join in person, virtual attendance is available too, so you can join us no matter where you are! This month, we have **Owain Jones** talking about building friendly content editing experiences and **Markus Johansson** talking about building packages for Umbraco. **Owain Jones - Unlocking the Full Potential of Umbraco: Building Friendly Content Editor Experiences** Umbraco is often called "The Friendly CMS", and it absolutely can be when we, as developers, make the most of what it offers. In this talk, I’ll show how we can utilise Umbraco’s built-in features and community packages to build intuitive, efficient, and friendly experiences for content editors. **Markus Johansson - Extending Umbraco like a Swede** In this talk, Markus will share his learnings from over 15 years of extending Umbraco. We’ll get a brief overview of the possibilities introduced with the new backoffice “Bellissima”. He’ll also give us tips and tricks that is useful both when extending Umbraco for a specific project or publishing a package for the Umbraco Marketplace. There will also be food, drinks and some friendly socialising. What's not to like? 😄 Whether you are an Umbraco novice or a seasoned developer, this is your chance to meet like-minded people to talk about our favourite friendly CMS! No matter what your role is there will be something to learn and your chance to meet other members of the Umbraco community from Kent and the surrounding areas. Venue The meetup will be at Dragon Coworking in Rochester (7-8 New Road Avenue, St George's Hotel, Rochester, ME4 6BB), a short walk from Chatham train station and with free on-site parking. If you wish to use the car park, please access via Gundulph Road, Rochester, ME4 4ED. You can then use the steps between buildings to access the entrance.

Whether you've never done improv before, or you've done it for so long you knew Del Close on a personal level, or anywhere in between, come join us! Swing by *Gresso's* for the **Columbus Improv Comedy Meetup** for some fun and games! The idea behind improv is to create entire scenes from scratch based on a suggestion from the audience. This can be done in game form, like *Whose Line Is It Anyway*, *ComedySportz*, or *Wild 'n Out*; it could also be done to tell stories, like *Middleditch and Schwartz*. Our meetup, which is central Ohio's longest running (and free!) weekly comedy event, brings the games (and occasionally different forms) for you to play in a safe, supportive, and compassionate environment. Not only is it a lot of fun, but you get to work on thinking faster on your feet, plus it's an excellent way to meet new people and make friendships that'll last a lifetime! Ask yourself if you want to join the **Columbus Improv Comedy Meetup**, and say "Yes, And" that you'll have fun!
