This group has been around since 2002, but we're new-ish to Meetup, so we never really know who's going to show up . . . which makes it fun. We have a large email list, completely separate from this website, and get about 5 to 10 people per meeting just from that.
Anyway, most importantly, this group is commitment-free. Some of our members attend nearly every meeting; others show up once a month or even once a year. The main rule is to bring something to work on for the first hour. No assignments. No prompts. It's just a solid chunk of quiet time that you can use however you want.
After the writing, there's a short break, and then we gather a little closer to take turns introducing ourselves. After that, we spend another hour or so doing an informal reading of our work. No one is ever forced to read -- that's not our style -- so at any given meeting, about half the people might end up sharing something. Some people read stuff they've been working on for a while. Others read what they've written during the hour. There's no need to bring copies because we read aloud. Each person gets eight minutes, which includes time for others to offer feedback, so we keep things moving at a pretty good pace.
People in this group have written and shared all kinds of stuff: novels, short stories, journal and diary entries, poems, personal essays, memoirs, plays, screenplays, articles, dialogues, outlines, limericks, newsletters, blogs, kids books, science fiction, erotica, comedy, book proposals, cartoon strips, horoscopes, wedding speeches, eulogies, and song lyrics. Anything goes, and the same is true for your writing experience. You don't have to be published or submit samples in order to join. The purpose is to have a varied crowd and a relaxed setting where we actually do some writing and have a chance to hang out and meet fellow writers, and since people often ask, we're mostly in our 20s and 30s.
We get together every week or two. There's no regular location because we usually meet in people's homes all over the place. (If you can host, please speak up!) Twice a year, we meet at a big, antiquarian bookstore in midtown. In warmer months, we meet semi-regularly in Central Park and other outdoor spots. We've even taken a few road trips as a group, but we almost always stay within MetroCard range. Once per month (ish), we meet on weekend afternoons, but we usually do our thing on weeknights from 7:00 until about 10:30pm. People are welcome to show up late or leave early, so don't worry if these times aren't ideal. Can't make it for the writing hour? No problem. Come after that and check out the readings.
We don't have a set schedule. Some people are never free on Mondays, for example, while others can never make it on weekends, so we meet on different days of the week to accommodate everyone.
Finally, this group has always been free (and will remain so for people who are already part of it), but because of the cost of advertising on Meetup, there's a suggested donation of $1 -- not per meeting, but just at the first one you attend.
That's it. Sorry for the long-ass description, but details are good, right?
