Sony E3 2010 Press Event Playstation Network Invitations

 So I got invited to the Sony E3 Press Event and I got the legal affidavit signed and notarized, but it also says

Driver's license or picture identification is required for check-in. Prior RSVP required

 nowhere in the email or the attached document does it explain if and how I'm supposed to RSVP, I sure hope i didn't miss my opportunity.

 If anyone has any answers, it would be greatly appreciated.

Have you tried replying to the email? Usually if companies want a response then they'll accept email replies.

Most people who will be responding to this post (including myself) don't have invitations, so you're probably in the best boat to work that one out. Anyhow, you obviously have to get in touch with Sony somehow to RSVP, and you better do it soon too.
