I haven't previously attended the San Diego Comic Con, but I guess if you want tickets you need to pre-register.
Note: This isn't to purchase tickets, this is just a registration to receive an e-mail to eventually purchase them.
You just fill out your name and address and such. You get a confirmation e-mail that you need to click on, and then you get confirmed!
Easy as pie!
And I am already registered!
Hopefully, Cosmic Book News will see you at the SDCC!
