OK convention-goers, geeks, costumers, kinksters, etc. If you could make up rules for other people at a convention or a conference to follow, what would they be? Mandatory showers for gamers? No touching the hot chicks in skimpy costumes without permission? No stopping for pictures in the middle of walkways? No hogging the Q&A mic at the end of a panel?  No hitting on the feminists who just spent all day lecturing about not wanting to be hit on?

Tell me, what do you wish other people would know about polite behaviour at conventions?  If you are new to conventions, what kinds of things do you wish people would tell you so that you know how to behave?

Also, convention workers (tech, volunteers, security, hotel staff, etc.) what do YOU wish con-goers would know or do at a convention or conference?
