I'm giving those who attempted to be nasty a warning.
Actually, you aren't. My subscription to the thread was cancelled when you deleted my post. I had no way of knowing my post was deleted except that I had the fortune of noticing this thread was getting activity so I checked. So no, you did not give me any warning. You put a warning in a storage room in the basement and then you hung a sign on that door that said "Beware of Tiger".
