I can't help you there but I can say 2 things:
1) there are no embarrassing questions here, if ya can't ask em here, where else Can you??
2) if you email jeff or susan (the TE admins) they can probably change your ID if you truly want to change it!
good luck and let us know how it works so we can pass it on to the next one!!
Life should NOT be a journey to the grave with the intention of arriving safely in an attractive and well preserved body, but rather to skid in sideways, champagne in one hand, strawberries in the other, body thoroughly used up, totally worn out and screaming: "Yeah Baby! What a Ride!"
