Sorry to keep this going but I felt as though this was an unnecessary post JakeStone. I think xfish's question was a valid question and we shouldn't discourage people from asking questions, all questions, here. This is how we all learn and everyone should feel welcome to ask anything. That is exactly what this forum is for, learning. Now he knows and I am sure there were others here wondering the same thing that also were educated by this question. Thanks xfish.
