User name change and removal

[LTD-Scott]

I had to register twice here because for some reason I never received the confirmation email for the first user name I picked. So I registered the second name to my work email address.

So could I get the user name "LTDScott" removed/deleted, and then change my current user name "LTD-Scott" to "LTDScott" (without the hyphen).

Thanks.
