@mhoeber @lamagnifica @stephensanchez @wedaly @gradyward Please review. This is a draft so things may be a little rough around the edges, and I have a couple of notes to myself inline.
- why exactly are you making the recommendation to limit the number? is it because of space limitations (that each response is a certain height describes a contributor to the problem, but not the problem itself I think)
- "each individual" is a bit redundant, are both necessary?
