Yesterday, we ran into JDVM, the Purple Owners Locker guy, at Epcot. He mentioned that the "Everyday Adventures of the Purple Van" thread has been retired. JDVM would have preferred to continue it, but Disney is uncomfortable with non-Disney commercial interests using Disney for business purposes.
I thought JDVM did a wonderful job of advertising for Disney, and that his posts were always very positive about WDW. But at the same time I can see why Disney is uncomfortable with an outside commercial entity using Disney to advertise its product.
