Really awesome info in that article:
"As Campbell molded the clay that was HHNVault, he knew there was an obstacle he couldn’t avoid. The original incarnation of the now defunct universal-excitement.com posted a leaked animatic from Revenge of the Mummy in 2003, approximately a year before the attraction opened. This led to a cease and desist from Universal’s legal team and action was taken to punish those responsible for leaking the file. This tarnished Universal Orlando’s view of fan sites, which left Campbell in a precarious place, considering Universal was his employer. Campbell called for a meeting with a member of Universal’s Legal Department to prevent recourse and repair relations between the company and its fan community. Campbell spoke at length with Universal about his Horror Nights project. The meeting fared well and Campbell was handed a legal disclaimer to place on his website that made it clear Universal and HHNVault were not affiliated. “I’ve seen the legal disclaimer copied verbatim elsewhere, which is funny because it was specifically written for HHNVault,” he mused with a laugh. Universal’s only proviso: Campbell couldn’t share content from Bill & Ted’s Excellent Halloween Adventure, a reasonable request due to the show’s satirical use of unlicensed pop culture being a potential target for litigation."
