Syntax: HOP channel ADD nick
        HOP channel DEL {nick | entry-num | list}
        HOP channel LIST [mask | list]
        HOP channel CLEAR
Maintains the HOP (HalfOP) list for a channel. The HOP  list gives users the right to be auto-halfopped on your  channel.
The HOP ADD command adds the given nickname to the HOP list.
The HOP DEL command removes the given nick from the HOP list.  If a list of entry numbers is given, those entries are deleted.  (See the example for LIST below.)
The HOP LIST command displays the HOP list.  If a wildcard mask is given, only those entries matching the mask are displayed.  If a list of entry numbers is given, only those entries are shown; for example:


  HOP #channel LIST 2-5,7-9
      Lists HOP entries numbered 2 through 5 and
      7 through 9.
      The HOP CLEAR command clears all entries of the HOP list.
The HOP ADD, HOP DEL and HOP LIST commands are  limited to AOPs or above, while the HOP CLEAR command  can only be used by the channel founder.
This command may have been disabled for your channel, and in that case you need to use the access list. See  /msg ChanServ HELP ChanServ for information about the access list, and /msg ChanServ HELP SET XOP to know how to toggle between  the access list and xOP list systems.
