This seems to be getting some very nice reviews.
The latest in forum software soon to be released commercially. Very different from what we have seen. Note the forum sections and thread listings for starters..

Other then the side crap on the main index page it is not that bad. Very modern and sleek looking.
Click on the avatars and such.. To see what it really does you are better off registering and playing with it.
Also a question? Is that where forum software is headed?
