Godaddy uses captchas on their renewal form but I also noticed that there is no submit button available until you actually click in the box to type the captcha. Has anyone tried anything similar, maybe a checkbox or something, and if so did it help?

The confirmation is a bit cheesy, but I am guessing spammers don't actually "run " the live page and therefore wouldn't set the hidden field. And, you could randomize the field for each page refresh so it couldn't be guessed. .......................

I would rather just use a regular expression. The reason is that email newsletter subscriptions are delicate. People are already hesitant about subscribing and I don't want to make them beg for it. I didn't think about checking if the first name and last name are the same, I may try that (and count my losses when/if anybody with the same first and last name tries to enroll). I may use Math or Lyla Captcha on other forms on my site though, so thank you for the links. -Aaron ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Introducing the Fusion Authority Quarterly Update. 80 pages of hard-hitting, up-to-date ColdFusion information by your peers, delivered to your door four times a year. http://www.fusionauthority.com/quarterly Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:259709 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4
