It is a privilege to be a Wikipedian, one who contributes information for the rest of the world to see. With such privilege comes the responsibility to be accurate and non-judgmental.
Even the best of us is human. No matter how hard we try to be accurate, we all make mistakes. When a mistake is discovered, the person who made it has the following obligations -- 1) Admit it. 2) Correct it. 3) Take care not to repeat similar mistakes.
