Channels are used to share information, documents in messaging environment and track conversations about topics.
Channel Types
Public Channels
Public channels are group channels where everyone in the area can easily join and leave. The group manager can add any person as a member of the group or any user in the system can join the group using the "More" button.
If public channels are desired, then they can be converted to private channel shape by "Convert to Private Channel" from the channel menu.
Private Channels
Private channels are private channels that are open to a specific group of users and cannot be viewed by those who are not invited. The group manager can add any person to the channel with "Manage Members" from the channel menu. Member users can leave the channel as they wish, but they must be invited to re-enter.
Direct Messages
Direct message channels are used to start direct messaging with one or more users. Channel members are determined when creating a channel and cannot be changed later.
