The guys over GV not only respond to you quickly, but they also give you a big hand to achieve your goals (no matter what it is), seriously!
I have been using Gravity Forms for a month or so, and I depend on the User Registration addon to signup up guest authors, very soon I will use it to submit posts on the front-end of the blog! (I must say this saved me a lot of time).
On another website of mine, I am using GV as my support ticket system, it's where my membership site members can send me their hosting and WP information, I simply store as an entry and grab the data any time I need it! (that also saved a lot of time try to find a member data in my email).
Great job, keep rocking WordPress's world!
