Age old discussion i know, but just looking at the FS/FT page, there are 8 threads on the first page that have been expired by duckmagicuk2, 5 from the same user, Pallan.
This is shifting all the active threads down the list, and if those have made there final bump, they haven't had chance to stay on the first page for long, shifted down by these Expired threads.
Why can't the last post be edited by a Mod, and the reason being 'Thread closed as requested?
Mods can edit any post, so why not do this. It shows they have attended to the request, and doesn't unfairly bump the expired post up!
Rant over :)
