I wrote the hack that you are talking about.
Once a member reaches the "full memeber" status, two new lines will show up in there profile just like the userdefined custom status hack. After this, they can assign themselves a custom glow color, AND a custom font color for there user name. Once again, it only works in IE, but netscape users will still be able to see the font color change.
If you would like to see it in action, i have it installed at my board. MEMBERS LOVE IT.

btw, the hack also has default glow colors for ranks, mods, admin, for people with under full member status designated in the cp general settings.
