I am considering buying the full version of the plugin. I currently have a site with Wishlist member, once the users register they are already registered on my wordpress site so this is perfect for assigning clients with WP project manager.
I want to basically be able to allow my registered users to submit information and then have limited access to see status updates on projects made through WP project manager.
Does the plugin have the capability to store information say submitted through Gravity Forms, Google Docs, Contact Form 7 or another method of input?
Any other input methods won't work. In the free version, users/co-workers were saved in custom fields. But in the pro, for performance improvements and role management, we had bring our own permission table. Even you could create projects with various plugins, inserting the user as client won't be possible out-of-the-box.
