Greetings!
I wonder if there are official servers forums.
I would like to talk to players in the same server I play (4521 PvE).
Do we have an official server forum?
No such thing as far as I’m aware. Occasionally there have been attempts to set up unofficial forums (for official servers) but in my experience they weren’t used much, or lived long. Exceptions may exist.
Instead, perhaps create a Discord server named “Conan #4521” and invite everyone you want to chat with to that Discord server.
