If you will run a download on Thank You's that come up on this board you will be pleasantly surprised. Many people do not thank you out of possible laziness or lack of some manners. But, regardless they did get the question answered and possibly did get the project completed.
Check out the Stuck light bulb question down about 10 inquiries, there is one thank you right there.
Most people ask a question and then gleen the answer and apply the answer and go on their ways. But they do come back again when another situation arises.
I personally feel that many people keep this site on the favorite list and use us all the time.
I, as well as Henry, Jay, John, pb, and a host of others try their level best to get to every question and attempt to help this person. But, there are a multitude of questionaires and only a hand full of answerers. That is why we love and ask others to jump in and help us when the back log gets heavy.
You are entitled to your comments either positive or negative, but there are more thank yous than letters or comments like yours.
