Good Morning,
We are attempting to use bulk user actions to search for all the teachers in courses throughout moodle. In 1.9, this was possible using the dropdowns found in the advanced section of admin/user/user_bulk.php.
Please find this screenshot: 
Currently, we can only select two roles.
Note: This is an updated Moodle 1.9 to 2.0.3 instance.
Cheers,
Brent
Well that is because you are searching in "system roles" and you should not normally have teachers in system roles -they should only be enrolled in the courses or categories where the teach. Moodle 2 has emphasised this by not having teachers (or students) as a site wide role. If you could do this in Moodl 1.9 it would have been because you had teachers enrolled site wide, in every course. Try searching for the teachers in course role instead -if I want to find teachers in my Moodle 1.9 I that is where I would look.
Thanks Mary,
The dropdown that allows you to search course roles did not have teacher or student as options either. This means that there is no way to ask the system to show all students or teachers via bulk actions.
I created a bug for this and it was fixed last night.

What is that bug reference, please?
