A lot of forums have this feature - where a Moderator can merge two threads of the same topic together, instead of deleting or just closing them. This is often helpful because someone could make a very valid thread, with very valid posts on it, but the only problem being the valid thread had been made before!
Also, its a lot of new members that make duplicate threads and they get put off by their threads being deleted, I've noticed. Merging 'em is a little less harsh.
What do you think?
