Greg, I can't get the shoutbox to let me post. I get an error that says I can only post once every ten minutes. Concerning your ag2 skin:

I think the server sees internal names in the folders in the pk3. If everything isn't named properly the server still thinks the files are the same. Make sure everything in the ag2 pk3 file is named different than the ag1 files and it should work. Somebody from LML clan uses the same model and I see it when she plays our server. I have long forgotten how to make a skin so I'm just speculating what the problem is.
