The paper you printed out is your order confirmation. The wording is a little odd on the site, I'll see if I can get it changed. You will have physical PAX East badges mailed to you by mid March!

I had a quick question - I'm starting a company making guitar controllers, and I would love to exhibit at PAX East. I've tried e-mailing the paxsales@paxsite address twice now, like it says to on the website, but I haven't gotten any response.. Is there some sort of minimum size a company has to be in order to rent space? Or has anyone else registered space at PAX before?

My birthday's the 27th. Should I show up in a hilarious birthday-themed hat? Oh yeah, I'm local, so my dorm could work if the hotels start running out of room, although my room is hilariously small and I'm not sure when vacations are.

My birthday is the 23rd, so this is going to be like my birthday present. I just bought my tickets for my brother and I, and I was wondering if a school ID would suffice as my identification?

Since you live in the US, your passes should be mailed to you, so ID isn't much of a concern. Although if you do end up needing to pick up your passes at will call (should they get lost in the mail), I'm not sure if a school ID will suffice. I think you will need your state issued ID (like a driver's license or permit).
