I ran a db query once to fix that... I should be able to find it using google.
Oh I misunderstood, my apologies - you want a plugin that does this automatically every time a username is changed, correct? That sounds like a great feature that should have been native vBulletin a long time ago and has mod of the month written all over it. Outstanding idea!i dont want to do that
i had a coder approach me to do some code for this to work and figured that as smart as you and ozzy are might add this to your arsenal
if not is fine too
