Users can submit (and resubmit) their solutions, until the deadline set up by the instructor.

This acknowledgement is needed: otherwise, a student could "crash-join" a group by simply listing some member of it as collaborator.
If A and B are in the same group (they have invited each other as above), and B and C are in the same group, then of course also A and C are in the same group.
If students fail to list collaborators, the instructor can add people or merge groups by clicking on the Merge Groups button in the submission view (see below).
