People are registering with my email!

Ok i don't know where to put this, but this is more annoying then you can think!

There's a site on forumotion (at least i think) that registered with my email alex[at]waddelersstaff.com. the site is webyardim.org. Its in turkish and i cant find a way to translate it. Can you please delete the account with it? Im thinking of cancelling the domain soon because this is really annoying

There's nothing really much to say except that you should contact Typlo (one of the administration) on this support forum to ask nicely for that forum's owner to change his/her email.
