I figure I may as well post these here since
is too lazy to do so himself.
Name Colour change & Prefix.
color: rgba(255,0,0,0.75) !important;
content: "//Prefix ";
Replace //ID with your profile ID (The number at the end of your profile URL.) And //Prefix with the prefix you want before your name. Remember to add a space at the end if you want it separated from your name. You can remove the text sizing if you so choose. If you want a suffix, Change :before to :after. Just be sure to begin your suffix with a space.
Also note, I used the RGBA format for colouring. So you can make your name translucent if you so choose.
I didn't come up with this code, I got it from Derfen Steve's "Color Spice" code and modified it, Although I think I was the first to use it in a profile.
I used this to change PWRBTTN's name to ______ You may want to change the line spacing for your font, I had to do that because the text looked too far apart on mine.
Nothing too complicated, But it does require a tad bit more effort in replacing text than the others here.
So if you have no CSS experience, Do a bit of reading.
