Submitted mirror domain

Hello,
I have inadvertently due to the passing of time submitted two sites.
http://www.thematstore.net - (a while ago)
http://www.thematstore.com - (recently)
I would like to delete one of the submissions ( preferrably www.thematstore.net) so I wont be kicked out of the submitting process.

Is there a way of doing so.

Thanks

No, you'll have to let it run its course, but we promise not to banish you for a single transgression.
