First of all, welcome to the Lunatic Cafe and its OOC Comm, Crossroads Mall. I'm a mod and you can call me Sil or That Tin Foil Chick.
If you're not new to the the Lunatic Cafe "chain" (also seen in LJ), then you know the rules and the basics. If you don't know them, this post is for you. We're going to do a quick rundown of things and if I'm not clear, you're more than welcome to ask questions.
( A Mini FAQ. )
( Role Playing in the Cafe: The basic info about the cafe. )
I know, this isn't the most detailed FAQ, but all you really need to do is read the user info and this to hopefully understand the basics.
