The Mailer is done and out of beta test. It ended up being a pretty neat design. One day I'll publish a little article about the increasingly sophisticated technology behind this web site. Meanwhile, I'll be shutting down the Yahoo! Group on Sunday. I'm particularly looking forward to the lack of a giant ugly ad from Yahoo!, but the new Weekly option is cool too. Mostly it will be nice to have it in our control. As my programmer friend Sean (whose help in this process was invaluable) says, building it yourself is always the right thing.
