I went on the site to register my iClicker and I found this:
"*Your student ID is assigned to you by your school. You may have more than one possible "student ID" (e.g. your email address, your Blackboard ID, a numeric ID). Your instructor likely has instructions about which student ID to use. Check your syllabus or with your instructor."
O.o hmm, what if i need it for more than one class and a prof wants the numeric ID while another prof wants the mugsi login thingyyy??? i'm soooooo confused!
