So, we have two candidates that would prefer not to be considered in a vote, yet due to existing rules will become councillors by default.

we had that discussion a couple weeks ago about the Board... if they'd like to, they can resign right away after entering function...
or at any time after that

So how do we proceed in case of that. Can they resign easier then if elected by votes? Or what is so strange with that?

There were candidates who mentioned they'd prefer not to be voted for, but since they nominated themselves or accepted nomination, they must have some desire to help out on Council.

Not a huge problem, imo. The worst case is that they can't donate that much time to Council matters, but will help out where possible and as needed.

That's not exact. It's not that I don't want to be part of Council or that I'm not willing to help, but I think it would be better to have different people in both groups, specially if Council was going to have only three members.

let's not play on the words, shall we?
there is no need to vote thus you got elected automatically.

question now is how will you simply leave the Council on its 1st reunion?

i don't agree with your "completely separate body" opinion.
communication between the two organs is going to be an issue; in order to avoid having a "left hand doesn't know what right hand does (decided, published, whatever...)" it is required to have exchange. the worst is to have each reading the meeting minutes of the other.
the next best thing is a member of the other attending meetings; certainly an improvement, but this leaves the "exchange" limited to meetings.
if one person is in both organs, the flow of information is optimal, as the person will always have the most recent status of both sides.

in fact, if both are going to remain, maybe such a duality should be institutionalised?

btw...
we didn't vote, so who is going to be chair of the Council?

since nothing in election rules says there'll be a council without election, and since votes are scheduled for 00:00, Friday, 2nd November 2012, I don't think there's any way to start new council before at least a virtual voting has happened in that very second and the responsible of former council announced the result of that election.
After that the new council will probably meet to elect chair

In the past, the council members have chosen their chair by whatever means they liked. If I'm not mistaken, the selection process often involved a spirited round of "Not it!"

I think having at least one overlapping member will be nice. Ivan, even if your only donation to the next Council is to act as a conduit for information between the two, it would still be unbelievably helpful.

Though logically, one can see that if one held an election, each nominee would get at least one vote. Knowing that, there's no reason to actually have it. (And in case there is any doubt, I publicly hereby cast my vote for all 5 candidates, if they want it or not. )
