Never experienced such expedient and helpful support for an already great free product. Highly recommended!
The only thing that bugged me was a slight glitch in the Wizard form creator. When saving the form, the lightbox would constantly insist on being just below my field of vision, and scrolling down caused it to jump down further, creating an endless white page where you could never quite catch up with the bugger. This, however, only occured on the part where you design your form. Changing to the e-mail page was all it took for the form to be saved.
