I sometimes read old questions in unanswered list to see if there're missing ones I can help. But a frequent situation is many questions has been answered perfectly while the OP doesn't accept as an answer. I'm sure about this because OP commented on answer with "Wow", "Great", "Thank you very much" etc. It is usually seen in groups of new or inactive users. The same phenomenon occurs on those whose answer is rather easy and simple as well as duplicated so that problems have been solved in comment, even not necessary for a formal answer. I wish some ways to put out these kinds of questions in unanswered list.

• @ShuchangZhang I'd like to chat, but first let's talk at the Crusade of Answers. Let me know if you have trouble using the chat rooms here. – rschwieb Nov 19 '13 at 13:47
• @rschwieb I've been there. – Shuchang Nov 19 '13 at 14:07

• @ShuchangZhang It suggests that you answered many questions that were not drawing much attention. This is a commendable effort. It is not rewarded enough with upvotes, but the system is trying to compensate for it by giving you a gold badge. (I just got Tenacious badge myself, which is the silver-level version of Unsung Hero.) – user103402 Nov 20 '13 at 1:55
