Ra'ed and Sima both suggested that Haloscan may solve the previously noted comments woes I was having. The side-effect, unfortunately, is that I seem to have lost all previous comments. Perhaps there is a way to recover them, but I can't get to it now. Anyway, even though the comments section was closed for only one day, it was annoying to have to take recourse to doing so. But it looks like this problem may be solved.
Thanks to those of you who sent me supportive emails.
