how do i start my msn name off with black and as it goes to the end it goes red how would i do this??

Like this:

[c=1]Insert your name here[/c=4]

cheers

Before you ask how to create a gradient highlight, here's the code: [a=0]Your display name[/a=1] where 0 and 1 are your color code.
And if you want to have both gradient highlight and text, here's the code: [a=0][c=1]Your display name[/a=1][/c=0] where 0 and 1 are your color code.
So basically, just end off with [/c=0], where 0 is your color code, for your gradient text and [/a=1], where 1 is your color code, for your gradient highlight.

Or just go into the WLM settings (Tools>Options>Display Name) and you'll find a new button that allows you to add colors and other style to your nickname.
