Heh.
I'm kinda doubting there will be much "chiming in" by the moderators; there isn't likely anything any of them know that isn't explained about this, 'cause it's really a very simple thing:

1. You want username changed.
2. They offer to do that for $24.95
3. cha-ching!
4. There ya go - enjoy your new personailty, and thank you for shopping at RosityMart.

Of course I do have to wonder how many moderators there are here who think this is absurd and...embarassing, even... I know you'd love to say so, too...but....  ;)
