Just another idea for the stress that the 'for sale' forum seems to create (too much ghoing on!).
How about if 'sold' items could be removed? I don't know who by - probably it would need to be the moderator which isn't great (unless some cunning stuff can be done with security to seperate 'for sale' from the rest of the boards). But it would stop a lot of the looking through posts hopefully to find that what your looking for has been sold (3 pages later).
Sorry, not a bug, I know
