Forum got "hacked"

Me and my friend created world of warcraft server and forums for it (This is great site! ^^) Anyway, I was on vacation, drinking beer and stuff, my forums got "hacked" by him.
But, as he created the forums with his email, there's not much I can do.
I cannot change my password, because he changed the email I use (I think so, because it gives the error that password and email does not match blabla)
I don't want to remake the forum, it has over 2k posts already and over 100 registered and active members.
Is there any way I can restore my password? I'll give the site's name if someone is willing to help me.

There is no way, since he is the founder of the forum.

Can I confirm the story any how, so you could restore my password or something?

Nopes, there is nothing to confirm since you are not the founder.

sad, why did you at least join that guys who is not trust worthy ?
be careful next time
