I finally realized that the members only page people are talking about has nothing to do with my forum account. After accessing it through the main site, I see that it was actually delivered to my leasing office (while I was home!) and they never left a note saying it was delivered -.- At least I can go over to my leasing office now and pick it up.
I still haven't received my badge or an email with a tracking number. Should I still be expecting a tracking number in my email? I tried using help.otakon.com, but it had a message saying badges do not get mailed. I'm guessing that message is either out of date or that was the wrong place to ask for help.
