Have to agree with Onisan - advertising for admins is probably not the best move. The minute your back is turned, they can destroy your server, even if they only have kick or ban priviledges.
If you find evidence of that activity in your logs later, sure you’ll probably ban them for it, but they’ll just move on, whilst your servers reputation will be in pieces for a long time to come.
Only give admin to people you know personnally, or have known for so long that you really know you can trust and rely on them to back you and your opinions on the server. Anyone else is a liability.
As for server forums… meh, I run some for my server on enjin. To be honest its more of a means of publishing server info and update schedules for regular players than anything else, and is somewhere to hang my clanpay link for people that want to donate. I’d love if it were different, but it’s not.
Every website, twitter account and random person has a forum these days, and you’ll find it very hard to get a new community to develop around using it as much more than a server status page for when they’re offline.
My advice, don’t put too much time into the boards, unless they really take off. Spend the time with your admins, playing the game and just getting to know the players that chose your server, out of the ~10k or so servers in the list, everything else will happen as it happens…
Anyhoos, good luck and remember to have fun
