My experience based on a sampling of one person (me) is when you visit a new forum, it is easier to just ask your question than to try to track down a previous post.

But for the moderators in these conferences, the same questions get asked over and over and over again and again and again and...

So that is why we advise new users to use the Search function first (it's in the blue bar at the top of the page) and then if the answer is not there, or if you do not understand, then post your question and we will do our best to explain.
