The terms of use thread says to PM a forum mod if you forgot password, but i remember the password, and also my forum account cannot PM yet

If I can't change the game account's email address, that is fine I am just curious which one i used in case i need to recover.
If any admin can handle this (if possible) I would much appreciate it! My forum account is the address i want the game associated with (if you can see this).
One more question: Where can i donate as I think i might since i stopped subbing blizzard a while ago.
