Question

I'm supposed to volunteer for Hightower's booth but he's never contacted me after the first time. I dont know anything about when I'm supposed to show up, what I'm going to do. Nothing. I got told that I didnt need to buy a bage but now I wish I did, cause I'm worried that I wont be able to get in. What should I do? I was going to buy one today but I saw that pre-reg had ended.
