remove. If you do not select this option, the channel settings do not
change.
7 Optionally enable the Refresh Channels on Add/Remove check box. This
refreshes each channel as you add or remove it.
8 To remove a channel from the Member List , select the channel in the
Member List and click >>.
Each channel must belong to a group. A channel can belong to only one
group at a time. You cannot move a channel from the members list to the
non-members list unless the system can assign the channel to another
group. If a channel has never been a member of another group, the
system cannot determine a group to which it can move the channel.
Therefore, it cannot remove the channel from the member list. If a
channel has been a member of another group the system moves the
channel to the group of which the channel was most recently a member.
Example: By default, the system creates two groups, Group 1 and
Group 2, and places all channels in Group 1. If you try to move a channel
to the non-member list of Group 1, the operation fails. If you select
Group 2, click
Membership , move a channel from the non-member list to
the member list, then move the same channel back to the non-member
list, the operation succeeds because the channel was previously a
member of Group 1. If you then view the Group 1 membership list, it
contains the channel you just removed from Group 2.
