Moodle. It's fun to say, and fun to play around with. I've spent a good part of the day playing with Moodle to set it up for use on a project. Well, that's a lie. I spent maybe 10 minutes to set it up, and the rest of the time messing around with modules, themes, courses, lessons and activities to see what it can do.
In my early experimentation, it seems like an amazing and flexible LMS. Looks like it will be able to do everything we need for this project, and I'd be surprised if it couldn't be tasked as the campus LMS as well. Lots of institutional and political reasons why that won't happen any time soon, but the software feels pretty close to ready. I know Athabasca is running their campus on Moodle (and ELGG), and I'm wondering what they're finding about large-scale deployment of Moodle...
