For suport issues like this, it's better if you post in one of the support forums. Regarding forum name change, that can be done but since you already created a new account, well I guess that's another way of doing it as well.

Nvm on the blog i figured out a way to start a new account on the site using my current email that was on Dark Demon2. So any posts done by Dark Demon2 (notice the space) was done by DarkDemon2 (no space) and the Dark Demon2 account will no longer be used.
