There is no cooldown timer -- I hate servers that do that. I see no reason to make players wait around some arbitrary time to move around the server.
There is no properties file -- the plugin's function is fairly simple and straightworward.
Issue /WARP [NAME] to warp to a warp location.
Issue /WARP [NAME] SET to set a new warp location.
Issue /WARP LIST to list all warp locations.
Issue /WARP [NAME] REMOVE to remove a warp location.
Issue /WARP HELP for hep using the /WARP command.
You must be OP to SET or REMOVE a warp location.
To install this plugin, copy the plugin JAR file to your server's plugins folder.
