WuFoo.com is a great way to get user input with slick, web 2.0 forms. It’s free for up to three forms and 100 entries per month, which means it’s a great option for blogs, small businesses, and community organizations that want to collect a survey, a registration, or contact info. (You can link it up with a PayPal account for in-form payments if you have a premium account.)
The form builder is very intuitive, easy, and fast, but be sure to test whatever you create before you put it out into the world! Also pairing your form with a privacy policy or terms of use statement is a best practice to reassure people that you’re not just harvesting their info. For anyone that’s gotten spammed by unsecured PHP contact form scripts, WuFoo is also worth checking out, as it supports Captcha and you can limit responses to one-per-IP if desired.
