How to find Linkshells and Fellowships? Balmung Server

[Fabbro]

Rare Monster Hunting & Tracking; There's a linkshell for this (bounty hunters)
Savage, Ultimate, Extremes challenges (synced); There's a discord server for this (Crystal raiders, I think, and UCR for ultimates)
General Chat of the Server (mature & polite); Either novice network if you have it, or the Crystal datacenter discord server,
Eureka & Bozja hard content. Discord server (Crystal exploratory missions or Eurekan explorers.)

Unfortunately the in-game social options aren't really used much. :T

Thanks for that, much appreciated : )

How can I join the "Bountyhunters" linkshell, please?

Are the Discord channels you mentioned open and easy to find via the Discord PC App (I'm fairly new to Discord, downloaded it ~2 months ago and rarely use it to be honest).

Thanks again for all the help.
