Regarding biographies, it's a debatable issue. When we change the names of heroes to forum users' nicknames, we do it only for THIS specific map. However, when we change names in the heroes' biographies, we are making changes to the dogmatic aspect of the M&M universe. Personally, I believe that the biographies of heroes should feature the original names of specific heroes whose biographies are directly related to the history of the M&M universe. This way, we emphasize the localized nature of the name change, rather than making a global correction to the History.
