Channels
Right-click Channels, click New, and then click
Channel.
On the channel's General tab, type the name of the
channel in the Name box. Be sure to precede the channel name
with a valid channel
prefix (#, &, %#, or %&).
On the channel's Access tab, select Secret in
Visibility to users. This prevents users who are not
designated members from discovering the channel through any query,
including enumeration queries (using commands such as
List or Listx).
In User, type a password. Anyone who wants to attend the
meeting must use the User password to join the channel.
In Owner, type a different password. This unique
password enables the person leading the meeting to join the channel
as the owner and invite the participants.
Set Number of users allowed in channel to the number of
participants expected to attend the meeting.
Under Allow only, select the Invited users check
box. This permits only invited users to join the channel.
Note Another way to restrict
access to the channel is go to the channel's Modes tab and
select the Accept only from channel members check box. This
blocks messages sent to the channel by users who are not designated
members.
