Now this is the kind of approach to discussion I like. What we need to do is find a way to keep track of all these issues, discuss them (separately or in clusters  whatever works best in various cases), then figure out how to implement what we decide, etc. Now, I really have to get to work now (sometimes I go to work in the middle of the night  quieter, no distractions) but let me quickly suggest the following. Would you mind if, later, I reorder these to bring related issues together, maybe group them into headings, and number them? Then it can be a kind of master checklist while we open separate discussion threads on each issue or cluster, referring to them by number, etc. As new issues come up we can add them under the appropriate heading in the list, and come back to it later if need be. Also, if we get stuck on something (e.g. "Need to get book X at library" or "EEng and CG decided to take a break on this one before they kill each other") we can just note that in the list as the status for that issue, and switch to another issues for a while. Would that be OK? I'd like to be the one to set up this organization, just because (I hope you will agree) I have a better mastery of all the "moving parts" in the Gage story and how they fit together.
In the meantime though, if you're eager to get started ASAP, let me ask you about two of your points so far:
"Missing Gage's time in New Hampshire prior to Chile." See, already here I wish I could just say "re Issue A3" or something. Can you say more what you'd like to see on this?
"Still glaringly missing the details surrounding his return home, illness and death"  same question.
   P.S. I may have little chance to interact tmw, but this is a good start  let's keep our cool and preserve it.
