Post additions for a review, get 2 other people as well as yourself to say it's ready for prime time, stick it in a poll, then if it gets a super majority (say 2 thirds), add it to the "House Rules" thread.
You can put as much or as little as you want in your proposal, but be warned the bigger the proposal the less likely it will be to pass. For example pieces of
Forceful Personalities would make good additions, but adding every single bit of it at once is probably a reach.
Suggested House Rules:
1) Puny Human is, IMHO, a good thing.
2) Ditto the App rules from A! (i.e. that you don't need a very low App to be Ugly). This would get rid of the "sometimes a zero is a 5" oddness.
