Due to the overwhelming response to the petition, our mail server is working overtime. In some cases, people aren't receiving their confirmation e-mails. This is due to random network conditions beyond our control. Please know that if you don't get your initial confirmation e-mail, reminders will be sent periodically so you'll definitely get one eventually--provided you gave the right e-mail address.
Please check your e-mail address for typos before submitting. I can't stress this enough.
