External server forums used to be very popular on platforms like ezboard/yuku. I'm still the admin for the Saryrn message boards, before it merged with Mith Marr and then, later, Bertox. They are still alive, but only get a couple posts per year. Some probably have Facebook groups, but they aren't well organized or moderated like forums used to be. I'd love to see Server formus here (I'd even volunteer to moderate for my current server).
Yeah, I was talking about the third party forums. They were bustling with activity [granted, this was a very different time.]
Povar has a Facebook (current) - peeps use it to announce open raids mostly but I do miss the old servers This old page has a list of old server links (Bottom right) but most or all don't work any more or are not safe any more. http://www.paullynch.org/tnzfaq/
I hate Facebook. I like to keep my irl out of my games. I'm thinking of starting a Discord for Agnarr.
