In the end, I probably made it a little more complicated than it needed to be, but the site has been moved to a better server environment with improved performance and room to grow. I’m hopeful this means an end to the downtime issues I’ve had over the last few months. They haven’t added up to much overall downtime, but each one of them is a minor headache for me, and I’d just as soon do without them.
Comments have been enabled again, and the site is back to normal. Thanks for your patience.
