Available for Gravity Forms?

Hello, I apologize for the delayed response, yes the Pro version of this plugin includes support for several forms systems including Gravity Forms. Unfortunately, my website where you can purchase the pro plugin was attacked a while ago and my web host shut it down, I am currently in the process of restoring it.

My website is back up, you can purchase the pro version which works supports Gravity forms at the following page.
