There are plenty of questions around for which there have been answers proposed but apparently the poster has never looked back at it (speaking of cases where there are no accepted answers). They merely increase the number of unanswered questions of the site. Anything that can be done?
Should there be a feature like a "community accepted answer" or something? Let us say if 5 or more users (non poster) find the answer as the appropriate one, they could perhaps accept it on behalf of the poster?
