@Oddsbod@DemousI do usually prefer to have everyone involved together in at least the beginning, so that we can figure out what will be the goal of the post. Just kind of helps to get everybody on the same page and set expectations as to what major points we need to address and whereabouts we'll need to end. I feel like establishing that sort of loose skeleton helps to limit collab bloat and overreach. Once that's established, everybody can really work on their own pace and it should remain relatively cohesive.
As far as the method we use to write this bad boy, I'm indifferent. PMs, the various pads, Docs, it all works for me, though I will say that the pads are probably the most useful what with their built in chatrooms, though the reliability of the connection leaves a lot to be desired.
