They do, but it cost 1,000 bucks which I do NOT have to dish out for a last name change. Plus an additional 500/year after that to keep the name.
So... looks like I am stuck with this name.
Also, it appears to be for NEW ACCOUNTS ONLY. That means that this does NOT apply to accounts already created...
IMVU offers screen name / account name changes, and then once changed the old name gets released.
It is also a lot cheaper. It typically costs 20-30 bucks for a name change token.
And if the name was from a deleted account, it becomes a "premium." It costs 100,000+ credits, depending. Which is about 100 bucks if you buy the credits from IMVU directly. A lot less than what SL offers. And mind you, the name change is USED TO CHANGE THE SCREEN NAME ON AN ACTIVE ACCOUNT. This does NOT apply for new usernames/avatars.
I wish ONE DAY Linden Labs would incorporate the ability to change user accounts. And then release them back to the public much like IMVU does.
