How do I delete an extraneous profile

[Dunearhp]

I just registered, then realised I had used an old username.
This is now my correct profile. How do I delete the other one?

if you made no posts on it I'm sure an admin could delete it.

No I have made no posts with it. The username is Phraedun.

Okies, I deleted Phraedun.

I went through a brief period of having to extravert and realized I was playing the role. So I changed my ID, after the move to this site and now regret it. Since INTPs can be changeable (God I hope I am not the only one), maybe there should be a "Chameleon Day" where anyone needing changes can make the request, and NGene can do it all at once instead of the one at a time.
