Duplicate email addresses should not be allowed.

[soloplxya]

Understand from the UG that students are only considered equal if they have the same student ID. However, from a functional perspective, all students should have their own email addresses so that the TA is able to send information to them directly. It might be better to account for an email address in the equality check as well.

Their Response to the 'Original' Bug

[This is the team's response to the above 'original' bug]

We have already specified in the UG, that only student ID is being checked for duplicates. Hence, the other fields do not have to be unique in TAPA. Since this is a suggestion, we believe that implementing our other features is more important than working on duplicate detection for fields that are not student ID for now, especially because the email address is not being used now in our existing features.

❓ Issue duplicate status

Team chose to mark this issue as a duplicate of another issue (as explained in the Team's response above)

• I disagree

Reason for disagreement: I still think that this poses to be a huge problem since the system can contain students with the same student ID but with different email addresses. In this case, how can the TA differentiate and recognize which email address they should send the information to.
