This may sound like a really weird suggestion, but is there any chance you changed the title at the last minute and forgot? I'm pretty sure I've done that before. lol Of course, I'd think looking at the other titles would have jogged your memory on that.
I'm so sorry that happened to you. And while the e-mail confirmation may be a good idea, I'm honestly not sure it would have helped in this instance, because that "Thank you for Your Submission" is like the e-mail confirmation. In other words, if you had gotten that screen, that's the same one that would have triggered the e-mail, and you'd probably have gotten a confirmation e-mail as well. (did that make sense??)
**edited to add** Grr. Never mind. I just realized that even if you HAD changed the title, you would have gotten e-mail notifications when you got comments, unless those went to spam, which they have been known to do.
