The rules - even though there aren't any - are on our main site HERE.
Speaking of rules, we do have them for the Facebook groups to make sure they're nice places to be. Otherwise they end up being just another "buy this" group like so many others on Facebook.
You can see our list of groups and find out about how they work on this page. You didn't know we had so many groups? We lose count too! Feel free to join as many as you like and tell your friends!
