Would it be possible to move the locked threads to the very bottom? I know we all want to keep them for nostalgia's sake, but scrolling through and pretty much seeing half locked threads can be a deterrent and it's a little messy. At least if they are at the bottom folks looking for the server forums don't have to select theirs out of a sea of locks. Maybe just create a separate sub-category for "Closed FFXI Servers" below the current ones.
Just a thought.
