@alias

command: @alias <player> = <name> attribute: alias

provides an alternate name by which the player is known. the alternate name is only used for players when referenced as '*<name>' or by commands that only take playernames (such as page or @stats). you may not set an alias on any other object type.

when setting an alias, the alias is checked to see that it is both a legal player name and not already in use. only if both checks succeed is the alias set.
