Well, to be honest, Imagineers don't really have much say in whether or not the Disney online games stay open or not. I met an imagineer and a convention (I don't want to say his name because I know how strict Disney is about what their workers say, so if you want the name just PM me) and he said he did work on VMK while it was still in the concept stages but wasn't told anything about it closing until me and a few others asked him about it.
So if you're going to try to save VMK, shoot for the Walt Disney Internet Group or someone in the company who has influence over these decisions. And don't give up on your dream, either! There was another Imagineer who I never got the name of who said he dreamt of being an Imagineer since he was eight. He achieved his dream, and so can you.
EDIT: By the way, sorry if I repeated anything. I didn't read any of the posts before me.
