Communifire is an Enterprise Social Collaboration platform, a more effective alternative to email and traditional intranets and a great way to reduce time spent in meetings. Empower employees to share ideas and collaborate on content while still retaining control over who can do and see what. Bring partners and customers in and limit them to just what they need to see to work closely with you. Everything a group needs is in one place with updates on all your groups coming to you in one place.

Maybe something like ELGG could be a base depending on your skills. I still was unhappy with that and started down a custom route but stagnated due to the time sink. Source: over 1 year ago
