Put me on the waiting list as well please.  I would absolutely love to be a part of this group.  I have several of 
the source books, have read all the books, and would happily spring for 
some of the released chronicles (Wedding Knight, the King's Landing, and
 expanded holdings publications, etc.) so the group could enjoy and 
partake in those as well and to help the DM along.  I'm new to roll20, 
but would be happy to do round-robin co-dm'ing as the group wants.  I 
created a homebrew adaptation ruleset using the rules for an Arthurian 
setting.  Can play pretty much any weeknight and any weekend day. Happy to help spring for supporter membership/etc. as 
well.
