Can a budget committee member be appointed at a budget committee meeting or does this appointment have to be made at a board meeting?

Budget committee members must be appointed by an official vote of the board at an official board meeting; not a budget committee meeting.  You could post a board meeting just before the budget committee meeting to allow the board to appoint the budget committee member.
