Whatever you do, DON'T sign up for this rally in Madison Square Garden with no intention of attending. I didn't do it twice using different phones and email addresses, and I didn't get a couple of text messages containing a confirmation number and one email each time to secure a total of four seats that I absolutely will not occupy on October 27th at Madison Square Garden starting at noon. I also didn't have to use a different internet browser the second time because using the same one twice didn't give me an error message.
Anyway, it would be terrible if lots of people reserved seats and nobody came.
