The company where I work for (1800+ Employees) is looking to enhance the personal relationships between its employees, allow a better collaboration and communication between departments and make it easier for the HR department to identify skills, experience and interests among the personnel (ex: we have some colleagues with deep knowledge of SAP modules and products, but during concrete projects it results very difficult to identify them and integrate them). Therefore, they want to implement a social network for our intranet.
We are just looking for the basic features such as profiles, discussion boards and so on, so nothing fancy. I proposed Community Server but my boss said .Net and java are no-gos. He wants LAMP and is not interested in a web solution like Ning, because of privacy and security concerns. It does not matter if it is Open-Source or commercial software. But it should allow a complete layout customization and must also have access from the outside world.
So my question would be, is there something like Community Server running on a LAMP stack?
Thank you very much!
UPDATE: We already have a Facebook page and a group. But my boss wants some features not included in Facebook such as a tag cloud in each profile page displaying skills and relevant proyects; and a feature like the "neighborhoods" from Last.FM, where you can group people with similar skills and interests and there is also the confidentialy issue (discussions about projects, clients, etc). So, any ideas?
