I get the default connection timed out firefox message. I tried posting in a few other places and I have no troubles. It even does it when I try and preview my message in that forum.
EDIT 12:49PM EST
Just tried to post a reply and that worked
Still unable to start a new post.
FYI this is the page I am on that displays the error after I try to make a new post
