TNF members cant' check the
[email protected] email account. That's limited pretty much to GM's. What you want to do is put the details in a support ticket.
If you purchased anything from the NF store for that account, digging up the "receipt" on google or paypal or wherever is excellent proof that you are in fact the real owner of the account. If you have any of that, include the dates and transaction ID of the purchase, and a GM can verify it against our database.
