4 Irssi knows these channel modes:
6 i - Invite only - People can't join to channel without being
7 /INVITEd, or being in invite list (+I, see below).
8 m - Moderated - People who don't have voices (+v) can't send
10 p - Private - People who aren't joined to channel can't see it
11 for example with /WHOISing people who are in channel.
12 s - Secret - Like private, but the channel isn't displayed in
14 n - No external msgs - Without this mode, anyone can send messages
15 to channel without even being joined.
16 t - Topic can be changed only by channel operators.
18 k <key> - Channel password (aka. key) - The channel can't be joined
19 without specifying the channel key (see section 6.2).
21 l <count> - User limit - No more than <count> people can join to
22 channel. This can be overridden with /INVITE with some
25 This is usually used for protecting channel from join
26 flooding, like some bot allows max. 5 users to join in
29 a - Anonymous - No-one's nick name, host or anything else can be
30 seen. All messages, joins, parts, modes, etc. are seen as coming
31 from nick "anonymous", this could be pretty confusing but nice
32 feature if you want total anonymity. This mode can only be set,
33 never unset. This mode isn't supported by all servers.
35 NOTE: there is/was one bug :) Channel operators can guess if some
36 nick might be in the channel and try to kick it. If nick was in
37 channel, everyone will see the nick that was kicked.
39 r - Re-op - If channel becomes opless for longer than 45 (?) minutes,
40 op everyone in the channel. This works only in !channels. This
41 mode can only be set, not unset by channel creator.
43 b - Set/remove ban. For example MODE #channel +b *!*@*.org bans
44 everyone from .org domain.
46 If someone from .org domain was already in channel before the
47 ban was set, he/she couldn't be able to write any messages to
48 channel (doesn't work with all servers).
50 Ban can also be overridden with /INVITE, although many stupid
51 IRC clients automatically kick the user out because they see
52 the ban and think that because of it the user shouldn't be in
53 the channel (doesn't work with all servers).
55 e - Ban exceptions. You could for example ban everyone from
56 *!*@*.org but set ban exception to *!*@*.host.org - works only
57 in IRCnet/EFnet servers.
59 I - Invite list. If channel is invite only (+i), people in this
60 list can join it without being /INVITEd - works only in
63 This is excellent for in-country channels that don't want
64 foreigners (spammers!) to join the channel, for example setting
65 channel's mode to +i and +I *!*@*.fi allows only finnish people
66 to join the channel. In addition to this, there's usually a bot
67 in the channels and sending /MSG bot invite command to it
68 /INVITEs you to the channel.
70 The ':' feature in channel modes is quite similiar, see section
73 O - Channel owner, the nick who creates a !channel receives this
74 mode. It isn't displayed anywhere, you can't pass it to anyone
75 else and you can't regain it again. This is needed for setting
76 +r mode in channel when it's first created.
78 o <nick> - Grant or revoke channel operator status from nick
79 v <nick> - Grant or revoke voice status from nick, only people with
80 +v (or +o) can talk to channel when it's moderated (+m).
82 You can send multiple mode changes with one mode command:
84 /MODE #channel +nto-o+v nick1 nick2 nick3
86 This would set channel's mode to +nt, give ops to nick1, take ops
87 from nick2 and give voices to nick3.
89 You can set only limited number of modes that requires argument in
90 one command. In IRCnet it's 3, in EFnet it's 4 and in many others
91 it's 6. If it's not known, Irssi defaults to 3. Irssi will also
92 automatically split them, so you can use /MODE +oooooo n1,n2,..
93 command to op 6 people and Irssi will split it to two commands in
96 See also: OP, DEOP, VOICE, DEVOICE, BAN, UNBAN
