For the quickest response, you can contact me by e-mail at jrporter[at]u.washington.edu .
I do my best to respond to any e-mails within 24 hours (fingers crossed) though I may be slower from time to time depending on whether I'm digging my way out from under a Kilimanjaro-sized pile of homework.
Alternately, you can get in touch with me through my Facebook Page if you're one of those enlightened few who steer clear of MySpace.
