Bungee Cord is a server proxy that allows seamless transition between servers. This works for bukkit and vanilla powered servers. Sadly we cannot use this with modded ones such as tekkit or FTB.
Upon first logging in you will be put in the server hub. The hub server will be a view only server which will like and display information about all the other servers. Once you join another server the only time you will arrive in the hub is if you go there yourself or the server you try to join is offline.
Most of the servers will be connected with IRC so you can see chat across all of them. There will be some exceptions and the vanilla ones will be unable to join. This will let us also provide more unique servers so we aren’t dependent on plugins to only work in certain worlds. Now we can have very unique servers that you can easily join!
