Aye, this should be really good. The only two issues are A) Does everyone have the expansion pack and B) How much difference in time zone are we dealing with?
I'm in US EST and can play pretty much any times. We can aim for two times a week, and then when someone can't make it, update them on what levels we're at so they can keep up.
EDIT: Also, to be less intrusive do the mods want to move this to a new topic called "Diablo 2 Play Group." Since it IS slightly OT in its current place.
