I would say a very high percentage of threads on the forum have been covered thoroughly in the past. Using the search feature can help folks avoid repetition, but I frequently am unable to pull up specific threads I know were made in the past on topics I need to ask about. Something in the way the search tool works, fails to find them, or only pulls up only individual posts with a keyword (which can be many,many pages of posts from a single thread) rather than a thread title. This makes wading through unwanted search returns quite tedious IMHO.
