Most of the mods on this site, especially the weapon mods must use the CC license they came with, if they use any portion of the original skin/models.
Please fix this.
All weapon mods that have parts of the original model/skin in them must be licensed as CC by-nc-sa - read license.txt (there are translated versions available).
I used this license to enable everyone to mod these models and skins, and to make sure these mods stay free for all to mod, if you don't use this license too, you are revoking these terms from your versions of my work - leaving future modders in an unclear licensing situation. This is not intended.
Please use the license.txt found in the respective model folders and simply add the author's name to the list of authors. It's very simple. No "readme" required, just the license.txt with added info about the mod's author.
