/accounts/a/users/b is the user profile page.

In the "Name and Email" section there are a set of controls: Edit | Act as User | Merge with Another User | Delete from the school.

In the "Login Information" section there is the "Add Login" control

In the enrollments section there are no controls.

I have people with over 100 enrolments and all I can do is scroll throght them seeing 2 at a time. I can't filter by any property, I am presented with all the completed courses the user was ever enrolled in. Unpublished courses. No subaccount info. This is a very unusable part of the site. My suggestion is that some effort be put into making this part of the page more manageable.
