The timeout on this forum is entirely too short. I have found that I have to log back in just about every time I try to post something.
I agree it's too short! Telling people to check the "remember me option" when you login can't see how that will prevent the board from logging us out. On most boards all that does is save you from entering your login details and from a security standpoint it's not too swift.
It remembers you. You click it and you're free to leave the page, browse the internet, smoke a bowl, come back and continue to browse DP. It keeps you logged in till you log out yourself.
