I've been seeing a lot of your posts in the wpnews section of my dashboard, so congrats on that!
I did do a Gravity Forms upgrade just yesterday on my site, so I came over here to see what the new enhancements were, so thanks for writing about that. I've had Gravity Forms for about a year now and glad I have it, even though I use few of the powerful capabilities.

For those people who can't invest the money in Gravity Forms right now, I recently heard of and just blogged today about JotForms. The UI reminds me of Gravity Forms and it is free to use (up to a point, see article) and also pretty powerful. They have SSL forms and it can be set up to accept payments through PayPal and many other related payment sites.

Thanks for keeping us informed!
