Hi Jazzid!
I'd write to Saz and ask him if there is someway to get the folks running amok in Wiz 8 who have played Wiz 7 to help you with your questions. Being as old as the game is, I doubt that there would be enough reason to have a separate board for Wiz 7 but you can ask Saz about that too.
Seems most logical to put them in the Wiz 8 board - but if you're getting ignored over there, you're welcome to post here!
