It's odd, I did figure it out but it was not where you said. It seems like the forum account settings are separate from the BV account settings, for me anyway, and to do this I had to go to "User Control Panel" from within the forum itself. I also have to log-in to both the BV, and the forum, not sure why.
Oh well, I have immortalized you in my signature greeney!
