Quake 3 Name Changer is a utility that allows you to design your own fancy quake 3 name along with colours and fancy letters. Not only can you make colourful names, but you can see what it will look like, using the preview window.
Another feature of Q3NC is the ability to change the name in all of the mods that you have in your Quake 3 directory. This gives you an easy way to keep all your mods up-to-date with your latest name appearance, instead of having to edit it by hand, or using the console.
When you click the save button, you will be presented with a small menu that allows you to choose whether you wish to save to all mods in you Quake 3 directory, or just those that you select.
