I've seen a lot of questions with good solid answers that have been upvoted repeatedly (even questions where the asker has commented on an answer and basically said that it helped them solve their problem) but the asker never officially marks any answer as the one that helped them. Is there an approved way to let the asker know that they should do this?
Also as a personal curiosity, I was awarded a bounty yesterday but when you look at the question it doesn't appear to have been marked as having an answer. Is this the way questions work when there's a bounty attached to them or did the asker simply award me the bounty but fail to mark the answer as correct?
