Gather the redditors in your town for a night out! or maybe even a night in! And scroll down a little for the RULES.
New Rules as of 4/9/12:
Rule #1: No more "does anyone live in (huge geographical area) type posts.
Rule #2: If a large, active subreddit exists for the location you're trying to arrange a meetup at, we will start removing the post and leave a note telling you to post there instead. Please see the regional subreddits lists here and here to check if your community has a large, active subreddit.
