I'm really sorry about the site logging you off every day... I don't know why it's suddenly doing that. I'm guessing that the site cookies are expiring after 24-hours, but I don't know what caused the change.
I'll see if I can adjust it in the Admin section, but in the meantime, please accept my apologies for the hassle!
ETA: Maybe it's the Automatic daily forum backup?
