I never realized Sinfest had its own forum. In fact there's two...

http://www.sinfest.net/forum/index.php

http://sinfest.net/phpbb2/index.php

Both are active and from what I've read, (which isn't much), there's different levels of moderation on them. Or something like that. And as you'd expect, there's less absolute praise for the new Sinfest than there was for the old. Some on the forums seem to think the current story arc is about them. I've just been following the comic though, and it looks more like a take on modern society to me.
