As all of you who have visited the site know, you can see its contents without having to register. To comment, you have to register.

Based on feedback, what registering also gives you is the occasional notice from me, the administrator, of matters of interest. Unregistered folks don't get this.

Your registering lets me contact you directly by fan-out e-mail on matters that I think are important and which need your attention. It doesn't happen often, but it does happen.
