Nothing much outside of the global rules, other than to remember that this is a board for discussing Meetings, Gatherings, and Get Togethers, so yes drama can be involved with these events. If something does happen, you are allowed to post it. This does not mean blowing up a thread with the drama. Remember, there is always having the choice of going through private messages, or just flat out ignoring the person who posted. Think wisely.
If you find anything that is obviously wrong, shoot me a PM, I really wish I don't have to actually say this, but some people would rather let it sit and rot.
