@firefly,
Not every one knows how to proof read, or deal with spell check. What world do you show up from? Have you walked away from your own city block? People, very smart people, have posted here after a stroke or two, and with impaired hands. At least one fellow had horrible trouble seeing. Some deal with mental difficulties. To all of these, you seem to wave your smart hand.
On the other hand, I infer from others that Bill may be better at english than he shows.
