The cost covers access for you to participate in your community. This fee is per community per semester/term.
For example,
- If you have only one class using Packback this semester, you only have to pay once for the entire semester.
- If you have two classes using Packback this semester, you would have to pay to join both communities
- If you take the same class for two different semesters and they both use Packback, you would have to pay the fee twice
