Pleasant,
If you use the menu button (on the bar with "Home Help Search, etc") to login rather than the "Quick Login" box in the upper right, you will go to a different page that will let you specify that you want to stay logged in. I don't know why these two methods of logging in are different....
I think there is a way that I can add the "Time to stay logged in" to the Quick Login. I'll work on it.
Heh, heh, figured out how to add this to the Quick Login!
