Making your own /Commands

[Curtis]

You can bind a key to a command, but it is impossible of what I know to make your own / command, the commands are server-side so I don't think it would be possible to make your own without an Admin or whoever works on the Gamemode adding it, however, you can bind commands to keys... Not sure if you could make /fish for example.

However it does sound like a nice idea, try suggesting it to an Admin :)
