CommandLimit
Will be ported to Sponge Powered? Of course!
Limit your players at a number of uses of a command
You can set, add, subtract the number of uses (per player and per command)
Commands are protected from aliases ("/essentials:back" or "/eback")
Tutorial
Step 1: installing the plugin
Step 2: add commands in the config file, by writing a new configuration section under "commands" (example: write "back:" under "commands")
Step 3: if you don't want to use metrics or the updater, you can disable them in the config (plugins/CommandLimit/config.yml)
Step 4: reloading the server
Step 5: type "/climit set Player back 5" to set the number of uses to 5 to the command "/back" for Player
