Syntax: copychannels <player>
This command copies settings‑‑such as color, brightness, and on/off
status‑‑from the channels listed in 'channel list.' It will not remove you
from any channels your other character hasn't joined. However, it will
attempt to join any channels your other character is part of, provided
there is nothing borrowing you from joining.
