The use of the "nickname" command can greatly simplify a player's gaming experience. The idea is to replace any occurrence of a given word in player commands with a much larger and more difficult to type chunk of text. In essence, it is a shortened tag that the server will recognize and swap out from player input.
(See "Syntax nickname" for details)
Note that only a single word is used as the nickname, therefore nicknames such as "bBox" and "big.box" are valid. but "big box" will not have the desired result. The latter will not return an error.
If the nickname command is used as "nickname big wooden box as bwbox", then the command "look bwbox" is translated to "look big wooden box."
