For those with 10k rep, I deleted my original question to split it off into its separate parts so we can better address it. What should we do to move forward on D&D 5e planning?
In reference to Grace's answer here: https://rpg.meta.stackexchange.com/a/3580/3529
What methods/data should we use to determine which RPG.SE users are sent advanced copies that SE procures for us for 5e's releases?
