I personally don't think it's necessary. I know for a fact that even the most nOOb question usually gets answered multiple times, and generally in a good mannered way. If things AREN'T working that way, then people need to let us know so we can deal with it....
One thing that is often overlooked is the power of the search feature. Some of the more basic questions have been answered hundreds of times, and quick search can often provide a guy with hours of reading directly related to his question or problem. That being said, there's nothing wrong with asking what some might a "stupid" question. We were all there once, and the open sharing of info related to K-series rigs is what CK5 is all about.
Just be sure to take the time to provide us with as much info as possible related to your issue. And the odd "thank you" really helps, too...........
