The structure of the Board to date is that of equals. The Board (by the current bylaws) may create a position of President, or Chairman, and appoint that title. But initially, there is no requirement to do so.

The Council has traditionally had a Chairman, elected by the Council shortly after they are elected, who is responsible for a few things on top of normal Council duties. (Announcing elections, speaking on behalf of the Council when one voice is needed, etc.)

Hold your horses there buckaroos, nominations don't even start until the 15th (and must be made the mailing list). We needed to announce 30 days before the vote based on the election rules, which is what this announcement was (that and the scheduled alarm went off a week ago on my N900, and I'm tired of hitting snooze). I for one haven't even considered if I'll run again, as I've been quite busy with my current duties, job, and life. I suspect most of the current Council are in a similar state.
