Nothing special so far but I thought I'd post anyway. I just installed this today. (Very nice, clean forum btw, thanks.) So far I've just written a little php on my main site to display the posts in the News section of the forum and integrated the forum with an iframe (still researching on what files need to be changed to do it right).
Note for IE users: I'm aware of the funky looking corner images on the site and am working to fix that...it's just not a huge priority at the moment.
