I'd like to participate in this round, but I wont have access to a darkroom for another month and a half yet. So it depends when we start. The 8x10" size is fine by me, if we want to do larger works we can always exchange one-on-one. 4 Rounds a year would be too many for me, I have other photographic commitments, so I would be sitting out periodically.
I'm with Carey on the themes, that would send me running for the hills. Maybe a seperate "shooting assignment" exchange on the side?
As always, I'm fine with digital means of printing as long as the source was analogue.
