The CHECK command allows one to check if there is anything awaiting them at
the Magical Post, using the magic of their amulet of communication. To carry
out this magical exercise, you must be wearing an amulet of communication.
Upon issuing the CHECK command, your amulet will glow, briefly: red if you
have nothing awaiting you, blue if there is something. It is truly
remarkable, this wonder that the mages of Faerun have managed to construct,
'tisn't it?
New: An automatic CHECK has now been incorporated into the WHO command.
