Hello. Complete newbie here.
Bought the game on PC back in around 2007 but could not register an account so this is my first time playing (don't really have the disk anymore)
Just got it up and working and totally clueless on what how and where.

Is there maybe a Nasomi community discord server i can join?

There's no discord. Try shouting in town for a linkshell, that's the primary form of communication.

As for being new to ffxi, you might try the getting started guide here: https://na.nasomi.com/getting_started.php

Also, welcome to the server!
