Thanks Helen,
I'll post the question on the forum you've pointed me towards, and if I dont get any respponses raise a feature request in tracker like you have suggested.
Going back to this thread, when I log in as a parent, and then go to the Activity reports for my child, and select grade, I dont see any grades. When I log into as a child and do the same I do see the grades that the teacher has put in. Any ideas on what I could be doing wrong. I've got all the user capabilities set to allow as well as user:viewdetails.
