I was answering this question and saw that it was tagged [molecular-dynamics] which surprised me, since it is nothing to do with MD. I thought I would edit it to include the tag [Monte-Carlo], only to find that it doesn't exist. That surprised me more. Although I can understand that some questions about Monte Carlo simulation might be better suited to Computational Science SE, or even conceivably Math or Stats SE, many such questions are intimately connected with the physics of the system, and would be a good fit here (IMHO). I can't find much serious discussion of this here on Meta.
If I finally get up to the reputation level needed to create new tags, and attempt to create [Monte-Carlo], should I expect some counter-arguments?
