YAY! SMF 2.0! I've had it for awhile on my forum. I think it runs more cleanly. Thanks, Iago, et al!
Yeah, spam control was going so horribly on the prior that I felt it was time to go to 2.0. Helped that they very recently released the "final" version.
As to the theme thing, I could be convinced to replace it with an existing, proven, 2.0-compatible theme -- but I don't want to go hunting for it.
(I'd prefer to preserve the dark text, light background thing and avoid any switchovers to dark background, light text stuff. Dark bgs can look cool but are murder on the eyes long term. At least eyes like mine!)
Make suggestions with links to the SMF site's listing of the alternative theme, and I'll consider it. (No guarantees, but it'll save me the hunt.)
