When you make the clicks and go where I told him to go...you will find this...How do I change my username?
To avoid confusion, we seldom allow username changes. However, we do occasionally make exceptions. Username changes are typically allowed for the following reasons:
you accidentally mistyped or misspelled your username when you registered, and you would like it to be corrected
you used your full "real" name as your username, and you would like to use a screen name instead
If one of the above reasons applies to you, or if you have another reason to request a username change, please describe your situation by making a new post in the Site Suggestions and Help forum.
