Channels are a way to organize your posts by subject and/or limit them to specific members of your group. Only Administrators can create channels.
There are three types of channels:
By default, there is a public "General" channel. This channel may not be deleted, because you must always have at least one channel, but you may rename it.
Administrators can create new channels by clicking on the "Add Channel" link that appears below your channel menu.
You may edit the name of any channel, and you can change the channel type (though you cannot change the status of a private channel or make a non private channel private). You may also delete any channel except the default channel. For private channels, Administrators may also add or remove the members of the private channel at any time.
To edit the channel information, navigate to the channel and then click on the information icon that is displayed to the right of the name at the top of the channel.
When you click on that icon, you'll see a screen like this, where you can change the channel name and, if it is private, add or remove the members of the channel.
Only Administrators can post to featured channels, but they can also move posts from any public channel into a featured channel.
You may have more than one premium channel, and your paying members have access to all of them. In addition, you can restrict a premium channel so that only your Administrators and Moderators can post new content to the channel, if desired.
