Forums Scripts & Popups Using the nick list color in messages

Thanks you, it's working ! I had to disable the "Auto Nick Colors" function. But... What can I do to... not have a long list of users that is feeding my list of "Nick Colors"...

But can you guys, help me to keep the "Auto Color Nicks" and the color of my fonts... because it's changed to white when I use your script. You can see it in the previous pictures that
I had share to you.
