I don't understand. Number of unique posters in the last 200 posts to a
newsgroup I understand,
and 647 to the (one) Python newsgroup I understand, but I don't
understand how you get
647 different posters out of the last 200 posts.

Oh, and Clipper is an old data base language, somewhere in the dbase
family.
