I know there are a few plugins out there that enable you to have multiple worlds and furthermore have portals accessing them. If you're interested in getting this plugin, Google it. Anyway, I want a server with two worlds, with two portals; One legit/vanilla and one Creative/full of mods. Could someone make a plugin that would allow activating a command when a portal is accessed. Such as changing your game mode, so when you enter the Creative world, it would enable /gamemode 1 but entering the vanilla world would disable it. Or the same thing but with another command. If this already exists, please post a link!
