Keep getting logged out

Whats happening with the site - it keeps logging me out which makes it very difficult to post anything and it seems to log me out in the time it takes to type a message. This is happening on my work computer as well as my home computer so I guess it is something to do with the site and not my IT.

I faced the same problem yesterday too.
I use Mozilla firefox. Tried 3 or 4 times & finally gave up.
Tried again today & it worked. Still using firefox.
bikeradar's doing server maintenance perhaps?
