+@SYNTAX:mode@
+
+Irssi knows these channel modes:
+
+ i - Invite only - People can't join to channel without being
+ /INVITEd, or being in invite list (+I, see below).
+ m - Moderated - People who don't have voices (+v) can't send
+ messages to channel
+ p - Private - People who aren't joined to channel can't see it
+ for example with /WHOISing people who are in channel.
+ s - Secret - Like private, but the channel isn't displayed in
+ /LIST's output.
+ n - No external msgs - Without this mode, anyone can send messages
+ to channel without even being joined.
+ t - Topic can be changed only by channel operators.
+
+ k <key> - Channel password (aka. key) - The channel can't be joined
+ without specifying the channel key (see section 6.2).
+
+ l <count> - User limit - No more than <count> people can join to
+ channel. This can be overridden with /INVITE with some
+ servers.
+
+ This is usually used for protecting channel from join
+ flooding, like some bot allows max. 5 users to join in
+ one minute or so.
+
+ a - Anonymous - No-one's nick name, host or anything else can be
+ seen. All messages, joins, parts, modes, etc. are seen as coming
+ from nick "anonymous", this could be pretty confusing but nice
+ feature if you want total anonymity. This mode can only be set,
+ never unset. This mode isn't supported by all servers.
+
+ NOTE: there is/was one bug :) Channel operators can guess if some
+ nick might be in the channel and try to kick it. If nick was in
+ channel, everyone will see the nick that was kicked.
+
+ r - Re-op - If channel becomes opless for longer than 45 (?) minutes,
+ op everyone in the channel. This works only in !channels. This
+ mode can only be set, not unset by channel creator.
+
+ b - Set/remove ban. For example MODE #channel +b *!*@*.org bans
+ everyone from .org domain.
+
+ If someone from .org domain was already in channel before the
+ ban was set, he/she couldn't be able to write any messages to
+ channel (doesn't work with all servers).
+
+ Ban can also be overridden with /INVITE, although many stupid
+ IRC clients automatically kick the user out because they see
+ the ban and think that because of it the user shouldn't be in
+ the channel (doesn't work with all servers).
+
+ e - Ban exceptions. You could for example ban everyone from
+ *!*@*.org but set ban exception to *!*@*.host.org - works only
+ in IRCnet/EFnet servers.
+
+ I - Invite list. If channel is invite only (+i), people in this
+ list can join it without being /INVITEd - works only in
+ IRCnet/EFnet servers.
+
+ This is excellent for in-country channels that don't want
+ foreigners (spammers!) to join the channel, for example setting
+ channel's mode to +i and +I *!*@*.fi allows only finnish people
+ to join the channel. In addition to this, there's usually a bot
+ in the channels and sending /MSG bot invite command to it
+ /INVITEs you to the channel.
+
+ The ':' feature in channel modes is quite similiar, see section
+ 6.2.
+
+ O - Channel owner, the nick who creates a !channel receives this
+ mode. It isn't displayed anywhere, you can't pass it to anyone
+ else and you can't regain it again. This is needed for setting
+ +r mode in channel when it's first created.
+
+ o <nick> - Grant or revoke channel operator status from nick
+ v <nick> - Grant or revoke voice status from nick, only people with
+ +v (or +o) can talk to channel when it's moderated (+m).
+
+You can send multiple mode changes with one mode command:
+
+/MODE #channel +nto-o+v nick1 nick2 nick3
+
+This would set channel's mode to +nt, give ops to nick1, take ops
+from nick2 and give voices to nick3.
+
+You can set only limited number of modes that requires argument in
+one command. In IRCnet it's 3, in EFnet it's 4 and in many others
+it's 6. If it's not known, Irssi defaults to 3. Irssi will also
+automatically split them, so you can use /MODE +oooooo n1,n2,..
+command to op 6 people and Irssi will split it to two commands in
+IRCnet/EFnet.
