You can share pictures, lists, and appointments with the members of your group. You can also chat with members and comment on shared items. A group can contain up to 30 members and can include members who are not part of your BlackBerry Messenger contacts.
The groups that you belong to are listed on the contact list screen of BlackBerry Messenger. You can also add a shortcut icon for the group to the Home screen of your BlackBerry device so that you can quickly access the group.
Depending on your wireless service provider or organization, this feature might not be supported.
