The community bot brings up a lot of questions that have been answered except the original asker never accepted. This causes a lot of old questions to be put into the unanswered pile and on the homepage. I think we need a privilege to vote for an accepted answer on a question older than a certain date 30 days for example. It will help us get to the "truly" unanswered questions faster.
example 1. Installed PHP module and restarted nginx but but PHP configuration isn't updating? 2. Setting max_allowed_packet for mysql on solaris 10
