I don't know why challenge tasks aren't shown in user's page.
I understand that for partial and tutorial tasks we don't get points so it is logical that they don't have to be displayed.
But why challenge aren't (while we get even 3 points for getting the best answer!) ?
Maybe it would be a good idea to print them with different colour so it would be clear how many challenge tasks and which each user did.
