Stack Exchange staff have announced an upcoming change to the way answer acceptance works.
Currently, the original poster of a question can accept one non-deleted answer. This does several things,
the question poster receives 2 rep, and the answer poster receives 15 rep
the answer has an added green tick mark below its score and vote buttons
the answer itself is pinned to the top of the list of answers, regardless of sort variable
This change will affect the last of these behaviors, removing the "pin to top".
The staff has indicated this may be configurable per site - each individual site can have this behavior turned off or left on (with the default setting yet to be determined by consensus and research).
Please indicate by voting on the answers below, which setting you would prefer.
Downvotes will be ignored for this purpose, as they add no useful information. Just upvote one, or both or neither.

In our case, it affects 114 questions out of 7,614 questions total.
The consensus is that we want to unpin the accepted answer with 5* votes for and 2 votes against it. (* I'm counting my own opinion as a vote since the system wouldn't let me upvote an answer I created.)
