Firstly, I really like this site and the forums within, nice work! What I think you could add to make it MUCH better would be to develop an advanced search page where you could specify that the search should ONLY be within the forums, or you could narrow the search down to a specific forum subject, say only within "Servlets/JSP forum".
The search at the moment seems to include pages from all other the site, half of which don't seem to be relevent to the searches I perform. I guess I could also try to be a little more specific with my searches!?!?
Well I hope this can be done... and thats my feedback :)
