. The rate until tomorrow is $25. I know it says $30 on the website, but it will actually only charge you $25 (it says $25 on the next page, so don't worry). Tomorrow, you'll actually have to pay the price shown.
Also, if you want to get in contact with the staff, going through me is a pretty good way. I'm the person most in contact with the actual attendees (you'll see me on the forum from time to time). You can just send me an email (email@example.com) with your information (name, email address, and inquiry) and I'll get you what info you need to know.
