[Using Sakai] Tests&Quizzes vs. groups :(

[will at serensoft.com]

Short version: some users can be added to a worksite group, others
can't? After adding users X and Y to 'group-member-list', click
UPDATE, and revisit the group... those user-names aren't there! What's
up with that?

Long version:

Course workste, with groups -- we add teaching-assistants individually
as users to their respective groups and... when revisiting the group
those user-names are NOT listed among the members of the group.
Anybody else find this and develop a workaround?

We tried adding teaching-assistants by role to the appropriate groups,
and THAT does 'stick' (as opposed to the individual usernames
disappearing from the group-memeber-list) but they still can't see
gradebook items.

We've renamed the teaching-assistant role to 'tutor' (using the !admin
> realms tool). Would that cause trouble? What's going on here?
