Im having similar issues here as well... This site is ultra slow for some reason. It is by far is much slower than other forums that I visit. For some reason it doesn't let me go to the home page. Says

M.T.1, you do not have permission to access this page. This could be due to one of several reasons:

Your user account may not have sufficient privileges to access this page. Are you trying to edit someone else's post, access administrative features or some other privileged system?
If you are trying to post, the administrator may have disabled your account, or it may be awaiting activation.

Who Knows?
