I keep signing out

Does anybody else keep signing out of this site? It's really annoying because I have to sign in again and then do my answer again! Please help me stop it!

Happens to me when I'm on my school comps for some reason... dunno...

happens once in a while here

Nope, I never do. I don't know if this site has one but check for a 'keep me logged in' or 'remember my name' button.

I get the same thing all the time so hopefully someone knows how to stop it...
