A check will be in the mail tomorrow. (I managed to use PayPal once, some years ago, but found it confusing & painful.) It would have been in the mail 5 days ago if this thread had been titled "Mudcat needs money". (What did I care what Max thought about what Bush said?) As it was, I had to wait for a cross reference from the moderated thread.
Having paged thru this one, I am moved to reflect, as I so often do, that the human visual system is a marvelous device for ignoring things.
