An upgrade has been added related to registrations -- which obviously won't affect anyone already registered. A "captcha" passcode has been added. Many forms on the net have these -- the small weird graphics with alpha-numeric characters smeared on them which you must type into a text field. These things prevent computers from filling them out on an automated basis, which some internet marketers are now unethically doing for the purposes of posting unwelcome and invasive spam on forums and guestbooks throughout the net. The one now installed here does not employ graphics but instead just works with a series of misspelled versions of numbers, like "elevwen". Not quite as difficult to crack as the graphic forms, but still a formidable task considering the reward, and much easier for me to create. I'm confident it is sufficient to prevent automated registrations.
I'm curious to see if it may be too cryptic for some people to understand. I don't think so but if it is, I can make further changes. You can see it on the registration page.
