I'm new to gravity forms, so this may have been requested before. I've been using a platform from SiteSell for about 9 years. One of the features that has developed over the years is something they call C2, or Content 2.0. It's similar to Gravity Form's ability to create posts, which I intended to take advantage of.
In C2, what happens is the visitor creates a "page" which is linked back to the originating page. The originating page also gets a link to this new visitor created page. So, first, I would requested that we are able to do this for pages, as well as posts. I'm content builder, and posts make hierarchies difficult.
I would also need the ability to insert a link back to the originating page, which means I would need to be able to pull the page title as a parameter (for keyword) and also the URL of the originating page. Since I use a theme with plugins that manage page hierarchy, I don't need to worry about the parent point to the child. However, that means I would need to be able to select the parent page (unless that could be dynamic, which would be my preference).
My goal would be to use as few forms as possible and make everything parameterized. But, if I had to build a form for each page, I would sweat it out, because it's worth it. My goal is to cast a long tail net off my content tiers. Hope that makes sense.
