Miss typed email when signing up, can't change it

Upon trying to change my email, it try's to send an email to the miss typed email address, which doesn't exist and can't be created as the domain was the part I miss typed (unless I wanted to go buy that domain but I don't wanna go register a new domain to change my email on this site). I use this username for everything so I don't want to just make a new account, how can I discard the non-existent email linked to my account?

You have exactly ONE post here.
SIgn up again but take more care next time.

You could also see if a moderator can help you out as they are pretty good at this type of stuff and know who to talk to if they cant do it themselves.

See that link that says "Report to Moderator" Its really quite useful and certainly not just for show.
