I spent most of today trying and failing to log in to the forum. Eventually got in with konqueror, but FF still no joy. IRC users who answered my Question said that the forum was OK for them. I eventually asked for a PW reset,and reset it to the same as it was always. I logged in fine. An hour later, after trying to reply I found I was logged out and could not log in.
Try to log in top left = page refreshes, no log-in screen offered
Try to post > log in screen. log in rejected > 'fill in form' form filled, > rejected ad infinitum
Also the times of posts seemed to be foobarred up, ie at 15:00, last post visible was from 07:00 or so.
Now logged in I noticed that things have been upgraded, whole new look to post form etc.
