These guys from particletree are awesome. 2 months ago they released a neat Web 2.0 app called Wufoo.

Wufoo is an online tool that helps anyone build and host amazing online forms. In a few short minutes, you can create a mailing list, a contact form, a marketing survey or even a complete customer management system.

I tested it and it´s really deadeasy to set up and to integrate in any blog you run. No need to go through all this tough CSS and hussle with floating divs. All you do is create your form and insert it into your website.

Wufoo offers different plans. As long as you do not receive more than 100 messages per month the service remains free. Check it out if forms kill you :)
