I’m about to install and muck around with Open Atrium as an social network intranet product for a client. It’s based on social networking software Drupal, and is free to download:

Social Intranet Open Atrium

Open Atrium is completely customizable. If you want a feature that’s not on that list, you can add it yourself. Read the documentation, specifically the How to Build a Feature section, to find out how to do it.

Atrium blogBlog: A classic blog for each group that has commenting, file attachments on both the post and comments, and granular notifications.
Atrium calendarCalendar: A calendar that lets you quickly add events, suck in iCal and other calendar feeds, and support single or multi-day events.
Atrium dashboardGroup Dashboard: Mini widgets give you a snapshot of all the activity happening across your groups. Think iGoogle, in that you can turn on what you want, turn off what you don’t, and arrange it all however you’d like.
Atrium documentsDocuments: A simple online handbook that lets you collaborate on documents, store and compare revisions, attach files, and once you’re done print out the final copy.
Atrium shoutboxShoutbox: Kind of like a private twitter, the shoutbox lets you share short messages, links, and information with just the people in your group.
Atrium casetrackerCase Tracker: A full ticketing system that lets you assign to do’s and create unlimited projects within each of your groups. The case tracker also lets you classify the to do, give it a priority, and manage its status.

Anyone got any experience on it? I’ve schlepped around with Drupal for about 4 or 5 years, but am not a guru- are you? Online communities within the organisation – what do you use?  And if the answer is Sharepoint, what’s your say on Enterprise systems like that?

Anyway, if you try Open Atrium and have a few words to say on it, lemme know your blog post or else comment here… Thanks! 🙂
