What does your team call its "leader"?

[Goobergunch]

For the first two years of 1168's existence, the leader was the President and was elected by the team. After that didn't work out so well last year, the Board of Directors (mentors) appointed a CEO this year, who was the team's student leader.

However, we don't have a very formal leadership structure. Essentially, whoever's in a best position to do the work ends up doing it, whether or not they're actually the designated officer/underling in charge of doing it.
