Category access

I thought about that but I wrote this plugin not to handle large ranges of posts, there are much better systems to handle that like Wishlist or S2Member or something similar. This is more for folks that want to sell access to for example Webinars with embeded content from Vimeo Pro or something similar.

Thank you for the suggestion though, but as of this time, I would recommend a membership plugin over this simple pay per post plugin.
