Notes have been posted!
My view on the discussions are much simpler:
Host: A person who picks the location for the meeting, this can be offered to a new member so they have a chance to build a nice location for a meeting.
Chair: A person who volunteers to run the meeting, they can work with the host to organise the pre-agenda. Any council member can be host if they have served a minimum term of 2 months on the council.
Easy Peasy.
