 He goes by acronymns?  Good gosh.  Hey!  DM! (sounds like a bowel movement)  COB!  (sounds like a logging head of staff out in the woods)  How about defining a symbol when it is first used, guys?  People might, sometimes be addressed by their job title but "goes by the acronymn" isn't accurate.  Do you have someone in your life whom you acronymnize?  Maybe a pet or something but c'mon, that's no way to write an encyclopedic sort of article.
