A company register to a website using a company field
Then, the administrator can invite co-workers to join the website.
When invited members join the website, they can only see members that received the same invitation. In fact, they are automatically assigned to the same company field. They cannot see others members of the website. They can only see content or members that received the same invitation + the administrator that sent the invitation. A great way to create closed communities. Fan Clubs, team of a company, a lot of applications !
Anybody able to create such plugIn ?
