Wikipedia does not have firm rules Wikipedia has policies and guidelines but they are not carved in stone their content and interpretation can evolve over time Their principles and spirit matter more than their literal wording and sometimes improving Wikipedia requires making an exception Be bold but not reckless in updating articles and do not agonize about making mistakes Every past version of a page is saved so any mistakes can be easily corrected   But I guess that really doesnt mean crap when you have some powermad freak around looking for someone to abuse does it
