Concept note — all comments

Note: comments left before Aug 25 8:45pm reference the pre-reorder page numbers (old p1 Need, p2 About, p3 Proposal, p7 Comms, p8 Geography). Comments left before Aug 25 ~5:30pm also predate the p6 split (Student Curriculum / District Cohorts) — their page numbers from 7 up refer to one page earlier than the current numbering.
