Ok so now when you or admin accepts an answer as best answer,
the status of Question is changed to answered.
This will also remove/decrease counter of unanswered tags
Most importantly it will cause the display of that question in the questions view page to visually indicate that this answer is 'Answered' - it will set the different css style to the answer counter, in case of this site this is blue background with white text.
Updates are now all pushed to github. Many classes where changed, as well as couple of Interfaces.
