Keywords are:  'pkok temporary'

The pkok command is used to register yourself for player killing.  With no
arguments, it gives a description of what it does.  With any argument, it
sets you to playerkilling.

For temporary player killing:
pkok <your name>

Once you register for temporary player killing, the flag can only be removed
by leaving the game and re-entering.

If you are killed by another temporary player killer, you will not lose
experience, equipment, or gold.

NOTE, HOWEVER, that being killed by a mob WILL take away your exp, and leave
your corpse wherever you died.  Because of this, it is illegal to pkill
someone in such a way that they lose experience or equipment.  This includes
summoning them to a mob, summoning a mob to them, using charmed mobs, or
anything else like that.
