I wonder it would be possible to extend the automatic logout period. It often takes me several minutes to read a good message and then rather longer to try a good reply and longer still to (hopefully) prune said reply down to some reasonable length. By that time I need to log in again to post.
I've looked in "My Profile" and didn't see any likely option which I control, so it appears to be something the administrator or installer sets.
Or maybe I'm just a whole lot slower or maybe I've missed some setting I should adjust.
