I have a website called "PostSecret" and when I ask people to leave their email address for news they have to fill out a CAPTCHA.
I am hoping to find someone who can help me create some code to avoid this and allow people to leave their email on my wordpress page without leaving it.
I can help you out with this :) Before creating a new plugin, have you looked at the Constant Contact plugin found here:
If that doesn't do what you need it to (regarding the email form) just let me know and I can throw something together very quickly for you :)
Have a great day,
