Please do me/us a favor. Don't reply to the folks that only come around to pump their websites. I'm sure you realize this, but, in my opinion, the only thing you only accomplish by replying is to push their post to the top of the message list again. I doubt you want to do this. They don't come back to see what's been posted regarding their message so again, in my opinion what has been accomplished? Why help them accomplish their mission?
Obviously, you have a right to say whatever you want. I just don't get why you would want to reply and feed the beast. Think about it please.
