A few days ago I posted a link on irc to a plugin that might work similarly to the old Multiverse plugin. Ideally I wanted Blacraft to have a plugin like that, so we could connect the regular world with the creative world and even other worlds as we used to. But I don't see myself having time to getting into Blacraft plugins anytime soon, unfortunately. I think hosting it on a separate server is uneconomical vs using such a plugin, if there is such a plugin.
