I've been catching up and just read the thread on this--Jim Leff's cautions, etc. Unless I missed something or something happened off-line, there wasn't follow through on it. We've talked about this a few times before.
How would we get started on doing this? It seems to me that the first task would be to identify questions or categories--not too many of them!--that we'd want to put into the guide. Then we could start trying to answer them.
