Im using SpongyCord, but do i also need to get BungeeCord then? 
Nevermind, i found info about BungeeCord, and the way it works.
I guess i will have some stuff to do…

Thanks alot for taking your time.
I guess i will drop this project, not enaugh documentation around this with Sponge, i found this: SpongePls [BungeeCord Forge Support]
But im not sure, I don’t wanna risk the server.
