A very big THANK YOU for this wonderful plugin. It's the best Form plugin I've used so far - hands down! Installation on WordPress 2.9 (upgraded, not clean) ran without any problems. Love it! Especially the Conditional Logic with extra fields popping up as needed is totally awesome! One tiny little thing: the time-field is missing a 24 hours option (where the date supports both d/m and m/d). Anyways, it's not a real problem, and looking at the rest of the reactions I wouldn't be surprised to find it in a future release.
I purchased the Developer Support License yesterday and will be using it for future customer sites. As a matter of fact... I am going to make some existing customers very happy. After all, it's the season! ;)
Thanks again and...
Have a very Merry Christmas and a Happy New Year!
