If you have another email address, couldn't you just update your email information for your account and then send in another application for the beta? Granted, it would probably not help that Bethesda has already started going through the applications but if you are that worried about it, might be worth trying.
I could change it, but I am sure they have already begun picking. Changing it now has the possibility of hurting my already slim chances. Not gonna be too big of a deal if i do not make it in, I am gonna have plenty of time after the 26th.
I just hope they tell us if we do not make it in, so I can stop lurking around my inbox.
