Web Sites and Forum Questions

I am a returning player from 1.0 that left when 14 went to pay to play. So My first question is this. Is there any way to reset my forum information like my nickname to reflect my new identity. And my second question is about the multiple web sites I needed to navigate. I still have my account information on SE account management and was able to update my new email address on it. This second site that I had to log into still has my old email address and there is NO option to edit it. While this may not make any difference I am OCD about things being displayed correct and this email is bugging me. Any way to fix that?
Thanks..

No one has any clues about this?
