I decided to make a simple guide for the people who don't know how to get on the server.
Download the EO client here: Endless Online.
Install the Setup or unzip the .rar file.
Open EOConfig or open the Setup.txt in your EO folder.
Change "game.endless-online.com" to "eo-utopia.no-ip.org"
Start the EO client and Create a new account.
That's all!
