List
Lists currently available channels.
/LIST [#channel] [-MIN #] [-MAX #]
You can also tell mIRC to show only channels with a minimum and a maximum number of people. If you specify a #channel then mIRC will only list information for that channel. If you specify wildcards, eg. *mirc* then mIRC will list all channels that contain the word mirc in them.
Note: QuakeNet supports server-side wildcard matching. To use this and save on receiving a lot of unneeded information, you must precede the wildcard match with a #, e.g. #*help* will return any channel with the word help in it. This method is much faster than mIRC's local matching method and saves bandwidth.
Note also that LIST does not return channels with modes +s or +p set unless you are on it.
Example
/list
Lists all available channels.
/list -min 5 -max 20
Lists all channels with between 5 and 20 users.
/list #help.script
Returns only information about channel #help.script.
/list #*help*
Lists all channels with the word help in it. (Requires server-side wildcard matching.)
