No, i know that option in the control panel.
I installed login v7.00 from Jim Goldbloom,
my members now have to bookmark a external html file for logging-in. But when once they are logged in, and they don't proparly log out, the next time they use the bookmark ultimatebb.cgi, it just skips the forcedlogout section and enter the forums directly, without noticing me that the user has logged in.
