I like the idea of the deadline for proxies. I think perhaps it should by by midnight before the slammasters meeting starts.
Furthermore, I was thinking that, perhaps, we should expect that, when someone sends a proxy, s/he also should give some instructions about how to vote; at least, how to vote on the issues already on the agenda.
I know this point would be hard to enforce, for what exactly (or even roughly) counts as "some instructions." So, I am not sure how to state this requirement in a precise and enforceable way. Still, I would like someone who sends me a proxy to also give me instructions concerning the items and issues to be discussed during the meeting. I'd like to be convinced that this someone does not simply blows things off, to clear the hoops, but rather thinks about the agenda and give some guidance about how the issues are to be decided. (I remember that, on one occasion when I was not able to be at the slammasters meeting, I send Mike henry several pages of detailed instructions and some general principles to be used when the votes are taken. Just saying.)
