OpenStudy (alexandervonhumboldt2):

Don't devalue the question/answer process! Don't provide someone with just the answer - explain the process, and help guide them through understanding the problem. Don't just provide the answer to a problem when someone else is in the middle of helping! But if you want to help, by all means, join in!
