Have you even noticed that it is a hell of lot easier
to write code after the fact then it is while you are
actually doing it?

What I should do is wait three days after writing a new program
and e-mailing it to Maarten Sneep and Matt Savoie before
I let anyone else see it. If I did that, I'd be considered
a genius, probably. Those boys sure know how to pick good
ideas apart. And now Paul is piling on.

This is not starting out to be a good week. :-(

Cheers,

David

P.S. Of course, you are right. I'll see what I can do
do when I get over the embarrassment. :-)
