No need for a link, it's about board games and the rules are (paraphrasing):

1. If you can't make it, let the host know the day before or morning of the event.

2. If you're playing at a venue, try to buy food or drinks from the venue. Don't bring lots of stuff from the outside.

3. Be kind and respect other people. Don't damage their games or act mean towards other players.

We're not super strict, but people have been perma-banned for sexually suggestive remarks or being assholes. I think we've had 3 or 4 really bad cases total. Most people get temporarily kicked out for violating rule #1 a lot.
