At one of the paces I fly at it's pretty common for someone to be flying without a pin if they ae the first one or three people there. We all know each other and show the courtesy to ask what channel the guy flying is on before we turn anything on. Then again, that same courtesy is generally extended to all the member that arrive as the day progresses so we usually don't even need to bring the pin board out unless we have more than 6 or more people flying that day.

I have to side with Flyin Tiger here. It's all about courtesy and consideration. If you are too lazy or in too much of a hurry to ask a simple but extremely important question then life must only be about you.
