SM is a Abbreviation for sorcerormickey among many other things.
Sort of like SM for Space Mountain, Splash Moutain...etc
SM or sorcerormickey was the master of cermonies so to say of the Mystery in Disneyland games on the website that started the Mystery in Disneyland game. Alex Loup is a currently active member of the website. While SM (sorcerormickey) was hosting the Mystery in Disneyland or (MIDL) game Alex Loup partcipated numerous times. She then decided to start the game on Mice Chat for all to enjoy after the the Host SM(sorcerormickey) left the website.
I think that Alex Loup Deserves a Big Round of Applause for bringing this game to Mice Chat and doing such a great job hosting it.
The Verdict is in on the Mystery in Disneyland V:The Mystery of the Missing Asteroid
