Apologies if this violates the rules on advertising, I won't actually link my server/Discord if that helps.
I spent a few weeks and set up a headless boiii multiplayer server that works for anyone using the boiii client to play Black Ops 3 on community servers. It was super cool getting to figure out the setup and I'm geeked that I was able to get it up and running successfully. I have it set up to fill with bots (5 max, so as long as there is 1 real player there's at least 6 in the lobby) and kick bots when real players join. It runs 24/7 and has a custom randomizer that shuffles all maps and game modes.
How do I get more players to play on my server? I know some of the other ones I can see have Discord servers, and I did set one up, but I'm not sure how to go about getting the word out. Any advise on getting people to use the server or join the Discord is greatly appreciated.
