HI All, Great thread, automated submissions can be such a pain in the butt
it's awesome to see different ways to address it. I didn't even realize the
W3C had a wiki about it.

Bob, thanks for confirming it works, I had always just assumed it would.

Karen, you can share that example with anyone you like.

Paul, I had never heard of a reverse honeypot -- I'll have to remember
that. You're right, these methods don't prevent human spammers but that's
part of why I went with the currency question...I figured it might be more
challenging for all the offshore companies that send SEO and related spam.

Sean, I'm opposed to the text message mainly out of privacy concerns. I get
very few unsolicited calls on my cell phone and I'd like to keep it that

Thanks everybody, I'm learning a lot from this.
