Alliedassault - modified skins and public servers (question?)

I have created several modified skins for my clan, it has the clan name and the player name on it.

I have all the modded skins in my main folder as do all of the other members of the clan who have the new clan skins. But for some reason we can't see them on a public server. If I host a game on my PC everything works ok and when I force models on a public server I see my modified skin. I used nemesis' tutorial to make the skin (big thanks to him) but am I missing something to get this to work?

Thanks for any help.
