Most of the graded assignments in the class are based on individual work. However, the overall project will be a team effort. The preferred size is 5 or 6 people.
It is your responsibility to coordinate with other students to form an appropriately sized team. You might use the class mail list if you are looking for people, or take a look at the spreasheet of students in the class (MIT certs required).
Once your team is formed you should come up with a name for your group. This name will be used to refer to your team throughout the class.
Use your team name as a basis to create an Athena mailing list for your group (moira list, check mailing list and AFS group).
