OK. I've tried doing this once before but now that we've got an entire forum about it, and most every organizer visiting here regularly, seems like a good time to pull this together.

I'll ask you to simply cut-and-paste this bit here, start a new post and fill in what you know - then I'll organize everything into this list here, ultimately creating a complete "guide". Sounds easy, right? OK.
