Sometimes when you try to open a page here, you may get a strange error (often with error codes 404, 418, or 500). It usually happens when the load on the web or database server becomes too great (since this site is running on the same server as a lot of other customers of the hosting company I use).
If you see one of those errors, wait a minute or so and try again. You may have to do this a few times before it starts working again.
If you find a link that you absolutely cannot ever seem to open that you believe should work, please send me a note using the Contact form on this site (if it’s up) or to email@example.com (if it isn’t).
