From forumotion help:
If you do not check the Log me in automatically box when you log in, the board will only keep you logged in for a preset time. This prevents misuse of your account by anyone else. To stay logged in, check the box during login. This is not recommended if you access the board from a shared computer, e.g. library, internet cafe, university cluster, etc.
