I'd like to propose the following:
2.1: All rule-change proposals must be made as new posts to the "A Simple Nomic" Google Group.
2.2: A rule-change proposal must include the word "Proposal" and the suggested Rule Number in the subject line. The post must be tagged "Proposal".
2.3: The initial text of a rule-change proposal must be in a mono-spaced font.
2.4: Rule-change proposals that do not meet the requirements described in Rules 2.1, 2.2, and 2.3 are invalid and cannot be passed regardless of votes made for or against them.
But I'll agree to the wording as it is now, I just wanted to open up discussion!
