I have to be honest and say I'm still familiarising myself with the stuff a mod can and can't do so I can't make any promises either way. The thing that possibly goes against it is that if you make one thread a sticky, people will then ask for their threads to be stickies etc, which means pretty soon the forum is a sticky mess! (Excuse the pun - it was intentional!)
The only stuff that should really be sticky threads are things related to the forum directly i.e. user guides etc and aything the ManUtd.com team put up for discussion. Sorry. I know it's a large thread and is interesting to look through, but as it is popular it will keep on returning to the forum front page anyway.
