yes im pretty sure i know how but i dont wanna go screwin around with things and mess up the server.. so i want to assure myself i was right...
i assume all u do is extract the pk3's of the skins u want to put in ur pak and start a new folder and jus keep cutting and pasteing into it then make ur own pk3 of it.. correct?
If you already know how to make a skin, and add it to a .PK3, all you need to do is make duplicate skins. Just rename all of the files so that no two are alike.
