Housekeeping update

Spammers have finally located my comments section, so I've added the "type the word you see" feature to fight the bots.

Also, I'm thinking of revamping the site again. I've always been partial to light gray on black, but dark grey on white would probably be an easier read. Which do you prefer?

FRIDAY UPDATE: Computer needs serious repairs which will send it into the shop, most likely. Unexplained, spontaneous reboots have stymied my last several posts over the last several days. I'm at a loss. I'm typing this as fast as I can before it crashes again. More as soon as I can resolve the problem.....
