I've used Sakai in the past, and Moodle for years now. (I think I used Blackboard once, years ago.) They're all a pain, but it would be hard to hand-code something that has even just the features that I use regularly myself. That being said, Moodle has some serious issues with dataloss if a user's session times out (and for a long time, the default timeout delay was just 24 minutes). If someone hasn't specifically clicked "Save" or "Submit" before time runs out (even if they were typing constantly the whole time), then those buttons invisibly turn into "Throw away all my work and make me log back in and start from scratch". It's horrific. https://tracker.moodle.org/browse/MDL-11972 https://tracker.moodle.org/browse/MDL-11972
