Usage:
/REQUIRE rwho.tf
/RWHO
/RWHO name=player
/RWHO mud=mud
Gets a remote WHO list from a mudwho server. The first form gives a complete list, the other forms give partial lists. Due to the short timeout of the mudwho server, sometimes the complete list is sent even if the second or third format is used (send complaints to the author or maintainer of the mudwho server, not to me).
Make sure you /load rwho.tf _after_ you define your worlds, or rwho will be the default world.
