Sorry. I understood what you said and I know that what I suggested isn't the same thing, but it seems to me that it does address the same issue because in general people won't know your email address. So I think it's the same thing you said except it just uses the email address in place of the user name, and the existing user name becomes the alias.

In any case, are you asking if something exists, asking how you can do it, or just suggesting a feature that you think should be in vbulletin in the future?
