Hey Sam Worm Lie, what kind of computer algorithm  quantum, continuous, or the dreaded otherwise  do you run on that you can ignore so many discussions (i.e., questions and observations) posters send your way?

Tell me it isn't like nine months?!

I asked you not to tell me that!

That's just great! Tia for the link. Will try, as usual, comprehend before reading. This way I preserves my preconceived biases. Must do that.
C'mon are you really a girl Sammy boy given your repeated issues with Mankind?
