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 doesn t mean crap when you have some power mad freak around looking for someone to abuse does it
