Why use colournick when the function is already part of msgplus?
julschennn,
To use colour in your name, open a conversation window, type /nick and a space and press ctrl-k. Then click the colour you want, type your name and press enter. If you want to use multiple colours, just use ctrl-k in your name multiple times, right before where you want the colour to show up
EDIT: That's if you have msgplus installed
