I've been playing on a Minecraft server for a long time. I recently started having team peak. I bought a rank on the Minecraft server (to have more rights etc.). How do I manage that the rank is shown in front of my name so that I can also join a room reserved for rank owners, for example.
It depends on which server it is.
People on the server will be able to answer that for you.
That's a question for server support, it's hard for us to answer that. Try to contact them.
The best thing to do is to log on to the Teamspeak server in support. These are the best ways to help you.
It's a thing that only administrators can change. YOU as a single person without high rights can actually do nothing but send a request for it.
