Hello! Can i change the forum email? i dont use my forum email (kazuka5@yahoo.com.br) so i want to change to (wowknu@hotmail.com) or (wizzyo_o@hotmail.com) please!!! 
First of all, NEVER post your email out in the open like this. (Unless you want to get spam mail or have accounts associated with those emails compromised/hacked.)
That aside, try sending in a ticket to Support asking to change your email.

Pick the Etc. category since that’s the only one that your question falls under.
Sorry for that, Thank You!!!
