Transplanting a Seattleite

We put a bunch of computer wiring in the walls during the remodel and have never actually used it, because wireless got better. I have forgotten quite how it was supposed to work. Also we have slow-to-turn-on fluorescents in various maddening places, and I have no idea why on earth we didn't just specify dimmer switches in all the places one might reasonably want them. One of these days we'll have a bunch of electrical work done.
