RE: Timed out
We are aware of the problem and we're working on it, trust me. It's going to take some time though as it will require a fresh install of the forum software and a migration of the database, which includes over 100,000 members, all their data, and the million or so posts that have been made.
In the meantime, try clearing your cookies, clearing your temp internet files, logging out, and then loggin back in WITHOUT ticking the "Remember Me" box. That has been working for most poeple, and although you will have to log back in if you close your browser window, it's better than not being able to post at all.
Thanks!
