Up to now I must say moodle will beat all. But nevertheless you sometimes get inspirations when you see other platforms.
Therefore I have a suggestion for a module, or perhaps it is the usermanagement:
I saw in some platforms the possibility that parents can inform themselves about their children online. I think it is a special feature of user management. When the child is a student in the plattform, a special account for the parents is built, where they can see the marks, the absence days and get in communication with the teacher. Another feature is, that the teacher can send a kind of newsletter (parents' letter) to all parents for general information.
I think when elearning will take place more and more in our schools such a parents account is very useful, as you then have all parties that are involved in education at school on board: Students, teachers and parents.
As I know, that moodle is often used at universities this "module" should be built in in a way that it can be deactivated, als grown-up students do not need something like that.
I hope that you can understand what I mean. Sorry for my bad English. I can unserstand English really well, but as I have no time for practice, my active Vocabulary is getting less and less.
