Only the courses where a professor is actually planning to use blackboard are listed. We create all courses, but the professor has to mark the course as "available" for the students to see it. In a typical term perhaps 2000 courses are eventually marked as available -- about 3/4 of all course enrollments.
If it's a UO course that you're taking this term, then you've been enrolled automatically. After logging into Blackboard, look under the "My Courses" heading. You should see links for all courses in the current term that (a) you are registered for and (b) are using Blackboard. If your class is not on this list, and you've been registered for the class for more than 24 hours (please verify your enrollment on DuckWeb), contact your instructor to find out if the course is actually using Blackboard.
You might see older courses from up to a year ago on your My UO course list because your teacher can make the course available again to students who received an "Incomplete" and may need access to the old course information to finish it. There is no way to make this only available to just the student in question, so all students who were previously in the course will see that it is active again. It’s nothing to be concerned about, but if it is a nuisance to you, you can hide it by doing the following:
Uploading a batch file for enrolling multiple users (students).
You may get help from CMET Consulting on using Excel if you run into any problems. Basically, you need to create an excel spreadsheet that has data on a single sheet. You can use the roster download from Duckweb and modify it to be as follows. On that sheet should be a single rectangular table with one row per person to add and the following 4 columns:
column A Username
column B Lastname
column C Firstname
... (leave columns D & E blank)
