@GuyCoder Matter Modeling had a normal SE election to select the pro tempore mods. The election was announced shortly after going into public beta and held a few weeks later.
@GuyCoder The most relevant post to your situation is this one: area51.meta.stackexchange.com/q/25863/181492. I expect the Thanksgiving holiday will push things back and they like to launch these sites on Tuesday so my the earliest I think it will launch will be Dec 8th.
@GuyCoder Also I'd add to this message that you can't change your vote made on a post after some amount of minutes, unless the post is edited, in which case you can freely change your vote (cancel your upvote or even change an upvote to a downvote)
