I'm a complete module/plugin newbie and I'm trying to find a solution for this issue, but I really don't know where to start.
I have a subscription model in which each month a bundle of digital goods is delivered to subscribed people only (a user group) however (and because the bundle must be accessible at any time through the year), I need to distribute it to the current users inside the subscribed group only, otherwise if I gave permissions to all subscribed users at all times, they could also access the previously released goods that they didn't pay for. So far I have the "bundles" as entries, and I created a entry field for the users. I guess I'm looking for a module that would "distribute" the bundle (entry) to the currently subscribed users (add it to their entry field) when it is released, and then manage access permissions in the templates.
I really don't know if that's the right path to take, and I don't know where to start so any kind of suggestion is more than welcome!
