I am trying to find a tool where me and my co-workers can have an structure like this:
(Web app) - State Foo - Business A - Project 1 - Project 2 - Project 3 - Business B - Project 4 - Project 5 - State Bar - Business D - Project 6 - Project 7
That we can use to keep track of the projects we are working on; where every 'Project' is just a place to post the progress of said project with text, styles, images, attachments, etc., and is only accessible to a certain 'Editor' and a certain 'Viewer' (with the corresponding permissions). It also must be private, so only someone with an account can access the content, a certain 'viewer' must only be able to see projects he's allowed to and all the users can only be created by a site admin.
The only thing that came close to it was using a forum app (phpBB); it has an structure very similar to what we need and has most of the features we expect, but it lacks the option to create users manually.
Is there another app that can fit (or at least come close) to our needs?
