So far have tried my original e-mail address as well as a brand new one. (yahoo.com)
Also tried a fresh g.mail address. No go. Message on registration for all three addresses states: Could not check this email: Please double-check: Needed for confirmation.
Check the "Spam" folder for your emails and make sure you don't have your settings set to delete spam immediately.
If that doesn't solve it, go enjoy your day, I have forwarded everything to the AHEvents guys and we will get this sorted out. You will have a bomber spot even if I have to delete a spot to hold it for you.
Thanks for your interest in the event.
