Every where in the game possible? : World of Warcraft General Discussions

Ok i know its possible to get everywhere in game but IDK how people get into instanced areas (except Emerald dreaM).... im not talking about making the terrain resemble the area, im talking about actually zoning into theese zones.
So to get to the point yesterday on my server Warsong US some guy got to Designers island.... if you /who'ed him it said he was there..... I would like to know how people get into instanced zones (except emerald dream i know that 1)

What is emarald dream?

check my videos "Void Walker Productions" and someone can close this post I figured out how the guy did it... You can check it all out in my new video
