+CHANNELMODE - DESCRIPTION
+------------------------------------------------------------------------
+NO PARAMETERS:
+     +n     - No external messages.  Only channel members may talk in
+              the channel.
+     +t     - Ops Topic.  Only opped (+o) users may set the topic.
+     +s     - Secret.  Channel will not be shown in /whois and /list etc.
+     +p     - Private.  Disables /knock to the channel.
+     +m     - Moderated.  Only opped/voiced users may talk in channel.
+     +i     - Invite only.  Users need to be invited or match a +I to
+              join the channel.
+     +r     - Registered users only.  Only users identified to services
+              may join.
+  ?  +R     - Blocks messages from unregistered users.  Only users
+              identified to services may talk in the channel.
+     +c     - No color.  All markup (color, bold, underline, etc.) in
+              messages is stripped.
+     +g     - Free invite.  Everyone may invite users.  Significantly
+              weakens +i control.
+  ?  +u     - Unfiltered. Receive messages that would otherwise be filtered
+              server side based on content.
+     +z     - Op moderated.  Messages blocked by +m, +b and +q are instead
+              sent to ops.
+     +L     - Large ban list.  Increase maximum number of +beIq entries.
+              Only settable by opers.
+     +P     - Permanent.  Channel does not disappear when empty.  Only
+              settable by opers.
+     +F     - Free target.  Anyone may set forwards to this (otherwise
+              ops are necessary).
+     +Q     - Disable forward.  Users cannot be forwarded to the channel
+              (however, new forwards can still be set subject to +F).
+     +C     - Disable CTCP. All CTCP messages to the channel, except ACTION,
+              are disallowed.
+  ?  +O     - IRC Operator only channel.
+  ?  +A     - IRC server administrator only channel.
+  ?  +T     - No NOTICEs allowed in the channel.
+  ?  +S     - Only users connected via SSL/TLS may join the channel while this 
+              mode is set. Users already in the channel are not affected.
+

+              PARAMS: /mode #channel +b nick!user@host
+     +q     - Quiet.  Prevents a user from sending to the channel or changing

+              PARAMS: /mode #channel +q nick!user@host
+     +e     - Exempt.  Allows a user to join a channel and send to it even if

+              PARAMS: /mode #channel +e nick!user@host
+     +I     - Invite Exempt.  Allows a user to join a +i channel without an
