Contactify is a free contact form creator. Definitely not as sophisticated as something like Wufoo, but useful nonetheless. You register, create a simple contact form and post the link you get wherever you want. If someone wants to contact you, they click the link. Presto, a contact form and no more email spam harvesting issues.
Contactify is the best, fastest and easiest way to allow people to contact you online, whilst never revealing your email address. Contactify provides you with a contactify link that gives you your own private contact form. (totally free!).
