I’m moving my site to a new host today—so that I can install new software to defeat various forms of spam. Once the process is complete, everything (including this blog’s address) will be exactly the same, from a visitor’s perspective. However, during the process, the site may be “down” for a time. Since anything I post today may disappear in the transition, I’m not going to write a substantive contribution. I should be able to post safely tomorrow.
