I have no idea if a plugin like this exists or not but if it does, tell me and provide a link to it please. I'm looking for a plugin that will make it so you can walk into a portal or something and you will leave the current server you are on and you will connect to another server. So basically it's like linking nether portals in multiworld (I think?) but it's moving you to another server. Is it possible? Or does it already exists?
