creating a new course (admin)

This is almost the same with or without LTI with Blackboard. The sole difference is, to enable logins from Blackboard for the professor, the WeBWorK User ID should be set to the NDSU ID.

Creaing a new course from the admin page

Adding TAs or other Professors

These privileged, non-student users should be created within WeBWorK with User IDs set to equal their NDSU ID.
See http://webwork.maa.org/wiki/Class_List_Editor for more information on adding users.
