This question has been clearly answered, but no check mark perhaps because the OP has moved on. But the Community user will dredge this question up again sometime in the future and will again and again until the OP marks the answer as acceptable, which may never happen.
Is there a way that people can vote to "close" the question or some other appropriate operation that will tell the system that the question is answered? It need not put in the check mark nor award 15 rep to the person answering. But we will get tired of these questions being repeatedly resurrected because the OP hadn't declared them answered.
This usually happens on trivial questions or those that are malformed or otherwise useless. It'd be nice not to have to see them again.
