Beginners are going to ask beginner questions. It's inevitable. The problem is that it's generally easier to ask something that others have already asked than to look around or even just to do a search. Suggesting people do one or both is great, but realistically, the level of compliance is never going to be or even approach complete.

If there's a good solution out there, I'd love to see it, and to see it implemented. But telling people posting certain topics is wrong seems more like an act of annoyance or frustration than it is a realistic suggestion for improvement. I wish it were so easy.
