The user submissions are stacking up and here is one of them. If you want to submit one, please hold off for a few days. I have a number of them under consideration. But, I will be interested in seeing it so don't discard your ideas. I just don't want to have 30 of these stacked up. Having said that, here is #8. I am thinking that this one may be recognized and might be answered by morning. Have fun.
