Cape Mod

I am making a mod that allows players to choose their own custom cloak and see it in-game. I want as many people as possible to use this mod so that when logging on the mikes revenge servers at least 1 other person has this mod. It is pretty much finished and the cloaks are visible in multiplayer and singleplayer. I need mikes revenge regulars to test out this mod to make sure everything works and you can see other players skins.Post your ingame minecraft name and I will pm you the mod(usernames ARE case sensitive) and add a cloak to your name. Once it leaves testing i will sendi t to as many people as possible so as I said before atleast one other person will have a cape when you log on

Example of the cape you will receive

Do these capes actually show up to other players who don't have the mod?
