help doing

Usage: doing <text>

The `doing' command sets text that can then be viewed by players using the
`who' command.  One frequent use of this command is to announce when one
expects to be back online: doing back at 23:00 EST.  To erase your `doing'
text, just say `doing' with no text after it.

The amount of space that `who' has to display your `doing' text can depend
on the widths of other variable-width columns.  You should make sure that
your `doing' text is legible when you are the only player listed by doing
a specific `who2' of yourself; you may also want to do this to see other
players' messages that have been cut off.
