I want to get some friends together and try to play D2x-Rebirth online. I see that they have a 'game tracker' https://www.dxx-rebirth.com/game-tracker/. But there's not a lot of direction about how to use it. Is it just... like, built-in to the game already? Literally all I have to do is go to my Multiplayer menu, pick a map & some options, and open it? I tried that, it didn't show up on the tracker page http://tracker.dxx-rebirth.com/, but I'm sure there's something silly I'm missing.
Thanks in advance! And again, apologies if this was already answered somewhere.

(PS: I can get them all set up with the game itself no problem, so don't worry about that -- just having trouble with the online hosting part.)
