A few weeks ago I was tasked with developing an Intranet for a client of ours. We decided to set them up with an instance of OpenAtrium, a Drupal project from the guys over at Development Seed. It’s a fairly new project, but what I’ve seen has really impressed me. I won’t use this post to detail the pros and cons of the system (that’s for another day, after we’ve had time to really test it out), but rather will guide you through the process of getting OA set up in the first place, and then in the next post I’ll show you how you can expand its capabilities using Features.
