hmm Perhaps it's a feature that was added in a later version of vb. As an admin of another board, i was able to merge one of my users who screwed up his username, made a bunch of posts and PM's, and then realized the mistake he made. He created a new username, and with the click of a button I disabled his older username, all of his posts and PM's went over to his new username.

I know there are probably some hacks and add ons with the current version of vb...perhaps an upgrade should be taken into consideration.
