/List [\<match\>] [-min \<min\>] [-max \<max\>]
*
Lists the currently created channels. You can specify wildcards in the match, but if you do not then only one entry will be returned. If no match is specified then '\*' is assumed and all channels listed.
Unless a single channel is requested the *entire* channel list must be transferred. Because of this some servers will disconnect you if you try this, and if not your connection may be tied up for a period.
Minimum and Maximum may be specified for the number of people you are interested in.
Note that not all servers support this fully.
*
/List \*UK\*
*
would list all channels with 'UK' in them.
