Seriously though. If you have a question or error message you should post it into Google first. You might find it's been asked before. Most of the time it has been asked before.
Then if you don't understand the explanation or require further help then ask your question and be sure to post that you already looked and found X but are having trouble understanding it.
It's always nice to see that people have put some effort and thought into solving their own problems.
For you the benefit is simple. Since most questions are repetitions of questions previously asked it is faster for you to use Google for your answer then to post and wait for replies.
