Apparently the new boards were having some severe issues, and Morrus had to turn off all the extra features (who's online, avatars, search, jump to menu's, etc.)
He also had to limit the number of people able to make a one time to 200. So if 200 people are making a post when you submit yours, it tell's you the server is busy.
Hopefully he will get the issue corrected and be able to remove the poster limit soon.
