MONITOR <action> [nick[,nick]*]
Manages the online-notification list (similar to WATCH elsewhere). The
<action> must be a single character, one of:
+ adds the given list of nicknames to the monitor list, returns
each given nickname's status as RPL_MONONLINE or RPL_MONOFFLINE
numerics
- removes the given list of nicknames from the monitor list, does
not return anything
C clears the monitor list, does not return anything
L returns the current monitor list as RPL_MONLIST numerics,
terminated with RPL_ENDOFMONLIST
S returns status of each monitored nickname, as RPL_MONONLINE or
RPL_MONOFFLINE numerics
For example:
MONITOR + jilles,kaniini,tomaw
RPL_MONONLINE numerics return a comma-separated list of nick!user@host
items. RPL_MONOFFLINE and RPL_MONLIST numerics return a comma-separated
list of nicknames.
