I would like to create a plugin/code that would assist in a small project that i have. I have a portal that i would like to incorporate user relationship and permissions functionality. So if user A has some documents they’ve added, And nominate user B and C to come register on the site, then user A will have user B & C as their secondary users that will only be able to view user A’s documents. User B must be able to View and Download those documents but user C will only get read only access. It must not be limited to just having 2 user below the parent user but multiple users with multiple permission settings that user A can determine upon nomination. I have also added this as a job if anyone would like to assist.
