Newbie...form content to post

I'm re-creating a large directory site from html to WP. I explored directory plug-ins but none let me have the control I wanted on the listings. So I'm setting it all up with posts using categories & tags to organize everything. I'm just copy/pasting each existing entry to a post and assigning categories and tags.

I was just setting up the Join form using a free plug-in and realized that ideally the content of the form would automatically be turned into a post (upon approval when paid). When searching I discovered GF. I tried to find info in FAQ & documentation but apparently I must buy first.

I did find the demo. It does look like there's a way to have form content be entered as a post so I suspect I can make this work.

Before I spend my money... what is your refund policy if it doesn't meet my needs? Also, I assume if I buy a single license and want to upgrade for more sites there's an upgrade path that doesn't penalize me for not buying more to start with?

Thanks,
Sheila

PS: I've been playing around in the demo. I'm trying to add post fields and customize them. When I click on edit they just window-shade down then back up. I assume that's some glitch in the demo. And I'm wondering if I'll need to populate the category choices or if it automatically makes the site's categories available? I have a lot of them so adding them individually will be a PITA.

Thanks Richard. I just bought the developer license. I've already got a simple contact form setup and a good start on my more complex membership form. I've run into some questions about using the Post Fields but I've asked for help elsewhere so won't re-post here. Looking to be a very powerful too. Thanks for your response.

Nancy,
Mostly I just used the documentation at http://www.gravityhelp.com/documentation/ I posted a priority support ticket because I had some unique needs and I've been told they're being addressed in the next beta release. I'm using the form to popular posts that are directory listings and I need visitors to be able to choose categories from a drop down. In beta 1.5 there's no default which means that if I have the same drop down option 3 times and they only have one category the default on the remaining ones will also be submitted. Not good.

Basically all I did was use the post field options I wanted. When I got to Body I had the option to pick and choose from all existing fields in the form and post categories, what I want to have appear in the post.

The other thing I'm waiting for in the next beta is the ability to have a hidden field, so all those who complete the form will automatically be given that category w/o having to choose it.

Hope that helps.
Sheila
