I like your concept of extra credit. I'm not big on extra credit. I say,
do the required work and do not worry about extra, but your idea of giving
so many assignments and letting them drop one? sounds like a good one.
PS note on the round robin: I must be the culprit or one with the digital
pictures, but I will be glad to round up the original work and forward it
for inclusion if you have an idea where my box is now so it can continue
with better samples. I don't want to be kicked out of the group. I really
am enjoying all the stuff. Fran
