The interface seems pretty slick to me. You can take a look at the
phpBB home page, and their
community forum. If you look at the
feature list, there are only a couple of things there that OpenACS forums doesn't do, such as avatars, smileys, themes, and the ability to send messages to user IM accounts.
However, those little features are pretty trivial to add. I think the really interesting part is their admin interface, which looks pretty slick compared to the OpenACS admin interface. It's not just a forums admin, but really the community admin tool. It's nice to have all the options in the left frame and opening up the working window on the right. It seems to have a lot of the same community-oriented features as OpenACS, just a little more asthetically-polished.
