"I often have hours of sleepless nights. What a godsend ICC is then! There is always a companion somewhere in the world to keep me company over a game." — Peter Brooker
The players are sorted according to the maximum of the active ratings.
(The B, b, d, L, s, and w flags described in help who1 adjust this.)
Each player listed has their rating to the left of their username, and
perhaps one of the following symbols: ^#.:~
^ That player is currently playing a game.
# That player is currently examining a game.
. That player is "idle" for at least 5 minutes (hasn't sent a command to
ICC recently).
: That player is not open for match challenges.
~ That player is currently giving a simul (playing multiple games
concurrently).
Also, in the listing, titled players will have their title displayed next
to their username. help titles lists the possible titles.
There are a number of optional flags, that select which players to show and
how to show them. Do help who1 to see them.
