People seem to [i]want[/i] to have rules for whatever reason...I'm going to trust that you can handle yourselves. Don't take over the roleplay, nothing too insane in terms of characters, don't be a jerk, stay active, etc. 

As for posting, this is casual, so post when you think you need to, as much as required. When it comes to describing your character, I'd like length, but while interacting, less can mean more, so do what you think there. 

Just be reasonable. 

There is one guideline, though, and to enjoy yourself. If you think you're genuinely not having fun, then talk to me and I'll see what I can do. 

Thx.
