How Do I Change My Gallery Name?

Tiffanie Gray - IDLM

I started with Daz Forums and Gallery a long time ago, even though I didn't do much with it. I'm starting to add more things, but it has my old name there as the Gallery name. I figured out how to change my forum name to something nicer, but I still can't figure out how to change my gallery name to the same thing as my current name.

Appreciate the help!
