In the Robotech.com forums MEMO posted this e-mail from SDCC that he received regarding registration for 2013.
Comic-Con 2013 attendee badges will be available for purchase online through the EPIC registration website in August 2012. There will be no onsite preregistration at Comic-Con 2012 for Comic-Con 2013 badges. Only those that have purchased a Comic-Con 2012 4-day attendee or 1-day attendee badge will be eligible to participate in 2013 online preregistration.
Professionals, guests of professionals, exhibitors, exhibitor purchased attendee badges, volunteers, staff, and press will not be allowed to participate in online preregistration in August. Open online registration for all categories listed above will occur at a later date.
Those eligible for Comic-Con 2013 online preregistration will be able to purchase up to 3 badges total. You will need a unique Member ID for each badge purchased. Eligible 2012 attendees may purchase badges for other eligible 2012 attendees, but they will not be allowed to purchase badges for those who did not attend Comic-Con 2012 or for any of the ineligible categories above.
Eligible attendees will be notified after Comic-Con 2012, via e-mail, with the date, time, and link for online badge preregistration. The notification will be sent to the e-mail associated with your Member ID account.
Please be sure to "opt-in" to e-mail correspondence to receive the preregistration badge sales announcement. To check your Member ID notification “opt-outs,” login to your account at https://secure2.comic-con.org/memberid/ and select the option “Change my preferences/unsubscribe.”
Thank you very much for your support of Comic-Con, and stay tuned for additional 2013 preregistration details!
As many of you know San Diego Comic-Con sold out very fast last year so I feel its important to pass along this information for fans who plan on attending in 2013.
