I didn't even think of using the search feature until I read someone telling someone else to use the search feature. I think many people are the same. They just don't think of that.
And the search feature is not fool proof. I searched for "version 7.5" and actually got 0 results when searching. I then made a topic called "New Features in Version 7.5" to make it easier to find. The new features in 7.5 was buried as a reply to another post. I would have never thought of looking there.
Plus you have to wade through a lot of junk before you get and answer. A FAQ would be useful.
After 7.5 comes out, I might help create one if I have time to maintain it.
