(no subject)

Well, I've now officially changed my e-mail address on the website and mailing lists. The old address no longer exists as part of our account (I suppose someone else could grab it; I don't know how long Earthlink holds old addresses out of circulation).

I've also now posted parts 3 and 4 of "Rheotaxis." I'm not completely certain that this version of part 4 is what I'll keep, but I don't expect that I'll make major changes. Well, not unless the feedback I get suggests that such changes are necessary.
