As per every other proposal (from the charter)
Changing the rules: proposing new sources and mechanics
Any player may propose that the rules be changed, or that new source material be allowed. To do so, the player should create a new thread in the forum with a title beginning with "Proposal: ". In the proposal, they should explain what the proposed change to the rules is, and why they feel that the change is needed. The judges, after allowing time for refinement and discussion of the proposal, will vote by indicating YES or NO in a post in that thread. (Judges may also mail their votes to
l4w.judges@gmail.com, in which case another judge should post the vote to the thread on their behalf.) In order to pass, a proposal must receive at least three YES votes, and the YES votes must outnumber the NO votes by at least two.
When that condition has been met for 48 hours, the proposal passes and becomes part of the official rules. If a proposal receives at least 3 NO votes, and NO votes outnumber YES votes by at least two for a period of 48 hours, the proposal fails and the matter is closed.
So right now it'd be tomorrow at 5pm EST (48 hrs after Kal's Yes vote) unless JNC, garyh, HM Gimlord and/or Lord S vote no, then it won't pass.
