JazzED!
That's how I used to roll! Well ok, not completely true, I began with regedit actually

There was a whole section on jazz2city called the color section (or something similar) where one could find directions for regedit to change one's name colors (which back then stuck even in CTF although they got changed, I remember i had my nick in green and GpW in red, and that turned to blue and I think it was gold?) or to change the colors.
And on the GpW page we had a downloadable skin for quake 3 fortress (all black with a logo) and next to it was the official jj2 fur we were supposed to use for cw's and stuff. Both listed under skins ofc
