Sign in Everyday ?
I know you've playing with some of the programming. All of a sudden I have to sign in every time I visit the site.
If you click "Remember Me" when you sign in- you never have to re-sign in; unless you delete your cookies.
If you do not click "Remember Me" you become logged out after 15 minutes of inactivity. (Leaving the board for any reason.) While 15 minutes is short- it prevents people from shared computers (Work, Schools) to use the forum without having to worry about logging out.
It happens when I use Remember Me.
