If you're looking for a feedback form, or a question form for your site that includes the ability to attach a file as well as a configurable captcha to avoid spam look no further. Easy to set up, easy to format the way you want, and as a bonus the resultant emails it sends are very nicely formatted (text or html) unlike most other form scripts you'll find out there. Add to this the great support from PlanetLuc and you'll quickly agree that it's a superb value for your seven Euros!
