This site has found a new home, on a VPS (Virtual Private Server). My prior host had let me down far too often by failing to install current technology and by repeatedly installing spam filters that silently blocked (and in some cases, permanently deleted) only about half of my spam, along with hundreds of good emails over the last few months. This, even though I asked them repeatedly to disable all spam filters on my site permanently, which they swore they had done. Very disappointing.
Fortunately, the move went smoothly. The result: the site is about 2000% faster than it was 24 hours ago. If you run into any problems, let me know!
