Grargh. Put in my order for tickets and the site crapped out with errors. Apparently this has been happening to a bunch of people. My card's been charged, but I have no confirmation e-mail or anything. So I sent them an e-mail saying "HEEEEEEEEEEEEY, um, just making sure I didn't just pay a bunch of money to sit on my ass in September?" I'm sure it'll get worked out. And if it doesn't, then I'll have a horrible experience to learn from or something. But I'm going to go with the "I'm sure it'll get worked out" scenario for the time being, considering it's the first two hours tickets have been on sale and a ton of people have been having errors. I'm willing to give it time.
ETA: Three hours later, I got my confirmation. HOORAY! Everything worked out okay. SEE?? Go positive attitude, go!
