Please don't double post.

And you can colour your display name using BBcode-like tags.

[b][/b] - Bold
[i][/i] - Italic
[u][/u] - Underline
[s][/s] - Strikethrough
[c=<colour>][/c=<colour>] - Text colour (specify in closing tag for gradient)
[a=<colour>][/a=<colour>] - Background colour (specify in closing tag for gradient)

There's also the old way using /nick and Ctrl+K so colours can be seen in older Messengers.
