Then why wikipedia showing it's date wrong or it needs to be updated?
As far as I know anyone can update information in Wikipedia. And I have also told that information in Wikipedia are not something you really should relay on. So who cares?
Half of that page is about theymos.
Whoever wrote the contents surly do not know the entire history. theymos is one of the important character for the forum obviously. May be some one can try to edit the information.
