First of all, I do want to thank you for the speedy responses and I would not mind to do this, as I am a server owner who look after three KF servers, and that with the amount of time I have (3 to 4 months, as my semester will start in Sept.), I do hope I can gather most, if not all, of the links for you.
Recently, the thing is that what I am doing for some of the files (Russian weapons) that involves changes in the textures, animations, sound files, and static meshes, I am changing the file names to include the version numbers. The weapons (Russian-made only) that I have spotted so far are RPG-7, PPSh-41, AK-47, SVD, and PKM. As for file changes that involve only the .uc files, I will leave those alone as I believe it is the responsibility of the server owner to modify their ServerPerks file to include these .uc files to avoid any conflicts, at minimum.
Also, I wouldn't mind to assist in updating the weapon mods list thread, as I do believe that in doing so will assist a lot of Killing Floor Players and server owners, whether it be setting up a server with the muts or installing the files as a player.
