Slightly off topic, but the one thing I have noticed with my email me form form with captcha (those characters you have to key in before you submit the form) is almost 100% of the people responding to my form, do not key in the characters first. They get an error message and then comply.

I know this because even though they don't key in the characters, email me form sends the message anyway but flags it as suspected spam. And as of now it has not been spam.

But I wonder if people just are not used to keying in those characters first, or if there is something not obvious about the process?
