Dave,

Quote: Ps. I believe this has come up a couple of times in the newsgroups.

I'm sure you are right; I only searched the more recent messages. Thanks for
the reply! I teach at a very small private high school so I wear too many
hats to do anything as well as I would like! These newsgroups are a Godsend
for the likes of me but often I end up doing it myself anyway.
