/hat - Toggles Sheriff Hat?
One of the possibilities.
If additional skins requires players to download files when they connect, I'm not liking the option that much. I don't like the fact that they'd need to download files just to play on the server 
The files of legit any modifications on the server are automatically installed on first time connection. It's one time only (unless new shit is being added) and should be fast as well as take up a couple of MBs on your HDD. Unless you have a 20GB HDD I don't see any problem with it.
