Is there any way to discourage people from "answering" a question if they do not actually have any kind of answer to the problem ?
Replying by saying "! don't know" is worse than useless ; or by misreading the question and saying "have you tried . . . " when you have already stated in the question that this is one of the things you have tried, with no success ?
To do that would mean every answer being reviewed by the AB staff before it was posted, impossible !
I know of certain users who regularly seem to post useless answers and if I see a post by them I look at it myself in case it is another 'hopeless' post that is just plain wrong .
^^^ Sibbers is correct - it's a useful technique when what seems like an important question has dropped out of visibility without a substantive answer.
i also agree, some people are in the habit of using this site for chatting and seem to forget that most questions outside of CB are looking for an answer not a comment
