Share 'Edu 2.0'

Hello all. I am searching for a free course management system that can be hosted completely externally. The one I keep coming across is Edu 2.0. I’ve taken a tour of its features and am very impressed. I was wondering if anyone else out there is using Edu 2.0 and can tell me what they think about it. Also, are there other free online course management systems worth looking at? Cheers.
