:plain: I wrote when I started this weblog that I would enable comments when I thought it safe to do so. Looking at my logs recently I have noticed that one or more persons have been trying to hack into the weblog through restricted access pages. Why is the net not as great as it could be? Because there are people who would wreck the work of others for a sense of perverse enjoyment. So as a precaution I will not be opening this weblog to comments from others. Until I find a way to protect the site better, things will remain as they are. If you are willing to give your email address and get a password, you can then use the forum to start (I hope) a discussion string.
