Well, in our case, you have to register to keep track of stuff, because without a userID you don't have anything to keep your place for what you have and haven't read. Which is, you know, useful, and the first reason I can think of to register.
To clarify tort stuff, and because I like the word tort:
(1) I think it's a great idea that the proposer of a proposal be allowed to withdraw it before the voting period begins, for any reason and without censure or tongue-waggling. (Unless the proposer prefers we waggle our tongues at him.) If the proposer, I don't know, breaks a leg and gets stuck in a hospital with no internet access, or even just changes his mind, there should be the option for the proposer to hand-off advocacy duties to someone else (and stick to the original time-frame).
(2) Said proposal, never having been voted down, should not fall under the moratorium for voted-down things.
I like both of the above. I will put them into Bureaucracy if people would like to consense there about them. Please let us consense about them, because then I will be happy and able to put them into my little Buffista Law document.
