Rule 1035 (Geoff: Mutable) Committee Scoring.
Before a proposal may be placed on the voting noticeboard, it must be seconded by at least one other player other than the proposer, unless that proposal is made by a committee (in which case no seconder is required).
The proposer may invite one or more players other than themselves to second their proposal. If and only if a player replies affirmatively to this request, that player is considered to have seconded the proposal.
The proposer must note the players who second the proposal, in accordance with Rule 107.
