Congrats on your persistence. I like the homepage - clean. I also like the freemium model packages. I have never seen the form metrics before and looks quite useful.
The form metrics feature was, in fact, based on feedback. I had some very basic form analytics in Tapefailure, but got a number of requests asking for more. I gave it a lot of consideration and came up with the current version as my initial solution.
Was that a feature based on feedback?
