So far this plugin is working great for my sites, and I applaud Mike's integration with CVita (and I hope they're paying for the built-in referral stream), whether I choose to use it or not, it's a great plus. The form seems to work without any drama so far, regardless of the GoDaddy SMTP issues that seem to have cropped up with other similar plugins. Works great, great options, and no annoying ads (like Google Docs has done).
My suggestions (if anybody cares) would be to allow for "if this answer or selection, then you can add this option" like Google Docs has as a premium supported tech support feature maybe. So far it's doing the screening it's supposed to do without those features. But the flexibility to provide greater screening capability would be great. Also the ability to insert images, video links, etc would also be great. Maybe for the future.
