I've gone through all the similar posts to this but can't find something with the same suggestion. I'm noticing a trend where OPs think that upvoting an is answer is marking it as answered.
I understand the reasons for them to be able to upvote an answer and not mark it as answered. However it might be helpful if, when the OP is upvoting an answer, they are reminded to and given the option to mark it as answered.
