For building you guys are going to need it. It's the old SOE wiki and I will get it up shortly.
I'm aiming to give builders FTP access, but to their own folder. They just need to coordinate with room numbers. I don't have this 'in' yet so it's not happening yet, but the idea will be that everyone can modify. Once we are more stable I'll probably revoke FTP access and keep it for people who actually upload/etc.
I'll have it up within a day or two after the game is released. Some people might know how the files work already (If they have seen SOEs files.) I haven't changed the room files much except adding a 'Store' value in the actual room, other then that it's the same deal for files.
