Hunh. Thought it was just me...
![Shocked :o](https://forum.arctic-sea-ice.net/Smileys/default/shocked.gif)
A couple weeks ago, one morning I got a (405?) error trying to access the forum (server not found, or something).
Sept. 8, I kept getting "Forbidden - You don't have permission to access / on this server".
And since last night, the "your session timed out while posting" message.
Got in now using the lower login screen, as others have described. At least persistence pays off!
