Why can't I remove a 'stumped' or a 'resolved' tag from my AskMe question?
The tags 'resolved' and 'stumped' have a special meaning and are treated differently at Ask MetaFilter. A question with either of these tags shows up in different places on the site to help others find them. A question tagged with 'resolved' appears in the list of Resolved Questions on the Answered Questions page. Questions tagged with 'stumped' appear in the Stumped Questions list on the Unanswered Questions page. This gives people interested in seeing complete answers or helping with particularly hard questions an easy way to find them.
Because these tags move the questions into different areas of the site, questions can only be tagged 'resolved' or 'stumped' once. This prevents the question from appearing at the top of these lists more than once.
