in some forums...(notably in 'live' chat places), there are 'ignore' buttons next to all names, and checking it will cause that 'person' to not be displayed in the forum...I have wished for something of that nature here when I am in the mood to read ONLY music threads.......but I would imagine that would require everyone to choose a 'category' for their posts...and still would not prevent silly thread creep and realted problems.

It may be best to not change too much.....this is an amazing setup as it is!
