Replay

Typing AFK puts your character in a tell-saving mode as follows: any tell
to you is stored in a special buffer, and can be seen later by typing
replay. This is useful when you need to leave the mud for 5 or 10 minutes,
but don’t want to miss tells. AFK shows up in your prompt until it is
turned off.

Tells to link-dead players are stored in a similar fashion, and can also be
seen by typing replay (unless, of course, the character logs off before
reading them).

You can also indicate an AFK message by typing AFK and people
will see it if they send you a tell while afk.
