The zeldaclassic.com email system has been fixed. If you want an account, go here to create one. If you already have an account, go here to login.
If you cannot remember your password, you can attempt a password reset. Unfortunately, if that doesn't work, I still haven't been able to gain access to be able to administrate the accounts yet. I'm working on it.
This is an excellent way to bring attention to Zelda Classic and AGN, so sign up today!
