Usage: /MODE [+|-]<modechars> <parameters>
  This   command   allows   the   channel   operator  to  set  various
  characteristics of the channel.  <modechars> is as follows:

    i          - Channel can exist without any users.  That is, the
                 channel is immortal.  Such a channel cannot have any
                 operators.  This is a Sysop command.
    l <number> - Channel is limited by the <number> of users.
    n <name>   - Change the name of the channel.  -n/+n is the same.
    o <name>   - Makes <name> a channel operator.  Note that any
                 operator in the channel can remove other operators'
                 access.  So, the original operator should choose new
                 operators carefully.
    p          - Channel is private.
    t <topic>  - Change the topic of the channel.
    w          - Whether messages are allowed to enter this channel.
                 Default is +w.
    m          - Whether this channel is moderated.  When moderated,
                 only operators can say things.  Non-operators must
                 /SUBMIT messages to operators and then operators can
                 /QUEUE POST these submissions.

  A  + or - sign determines whether the specified mode should be added
  or removed.
