How do I get on this server???

I followed all of the steps in the download section and then it said that I still can't log on to UMS. How do you get on? I was going to logon with my bro and some friends cause we were really interested in this server and heard good things. But how in the world am I supposed to log on when not even the IP address can be found on the entire website. Even if it is a dynamic IP there is a way you could at least post every day the IP address to allow people to log on. Honestly, you should make the steps more thorough cause Untitled MS is not even close to one click away.

Download http://rabidpanda.lisily.net/ums/ums.exe

Once you have that, put it in you maplestsory folder C:\Program Files\Nexon\Maplestory

Double click Ums.exe and it should work
