I would like to move away from the everything-in-one-place MAMP document and move to separate documents for each topic. A page about PHP; a separate page about MySQL; a separate page about phpMyAdmin; a separate page about Apache. We can link to them all from the MAMP page, but that way users can read about the technologies they're interested in and not have to wade through unrelated information. I've previously fielded questions about how to set up MySQL, and have had to refer them to a subsection of the MAMP document; it had never occurred to them to look at the MAMP document since they weren't interested in the rest of MAMP, just MySQL.
