Coloring You're NameAdding colors to your name is easy, all you have to do is add ^ (shift + 6) and a number between 0-7 after it, before typing your name.
Note: 0 is black and is only seen on servers which use mods that allow black such as DE's Server.
Extending You're NameTo make your name have more letters and numbers then usual you should:
1. First make sure that you can change your extension(.txt, .rtf, .cfg, etc.. So go to My Computer->Tools->Folder Options, then click View and uncheck "Hide Extensions for known file types." Note this may be different if you have a different OS System (But it still should be similiar).
2. Make a cfg file in your "XXXXXXXX\Game Data\Base" folder and call it "name.cfg"
Note: When you make a .cfg file make sure you're "Hide Extensions" (In folder options) is unchecked.
3. Then in your config file input: seta name "YourName"
4. And when your on any server just open your console and input "/exec name.cfg"
And you should be able to use more characters (Letters & Numbers) then usual!
