If we - or the leaders - would agree on an appropriate list of topics (flexibility a given here) for this project, those topics could be divided up with a topic per interested "editor" person - who would then search our writings using the "find" function and put something together. At that time, it might become necessary to contact people to ask if a specific post might be quoted from. This should result in a rough draft of a rough draft - at least we would have things somewhat sorted by topic, with no doubt some (only some?) overlap.

Just a thought, not trying to overstep any bounds!
