Just started looking at 1.4 and again I'm impressed 
.
A request I've had from a classroom teacher is though:
Can you have differing due dates for each group on each assignment? Classrooms sharing the same course don't often run exactly in sync.
Also, (and just a suggestion, another from someone who doesn't contribute enough 
) the 1.4 File/Web resource module is starting to get scary for non tech types. Would there be any value in hiding some of the advanced features, something like having a Simple/Guru mode.
Thanks for everyones hard work.....
P.S. Just finished a Moodle info session for about 10 of our local schools which went really well, and running another in Geelong soon I expect.
