Re: wp super cache deactivate files?
Hi Madloki,
The “don’t cache pages for logged in users” is a fairly sensible one to have ticked, obviously. 
It’s just to give maximum flexibility I think, as the plugin is used across many different kinds of sites.
If you look in the WP Super Cache settings, in the “Accepted Filenames & Rejected URIs” section, you can probably specify part of a URL (perhaps “forum”) which should mean a page isn’t cached. You can check whether a page has been cached by looking at the bottom of the HTML source code, where it should say in an HTML comment.
Good luck!
