Well, I got my husband entered after only three or four tries. Then tried myself and after a dozen attempts (each time getting the overloaded - try again message) I finally got a different error, this one saying that my e-mail address had already been submitted today. So I guess it went through on one of the times I tried, even though I didn't get a confirmation.
I was so hooked on the thread last year that I was actually disappointed when I didn't win - like I really believed it was going to happen! Here's hoping I can keep my perspective this year ;-)
Good luck everyone!
