Categories and Tags can be used for searching and organizing content in the course. For example, you could create a Category named “Chapter One” with the tags “heart” and “brain”. This would allow filtering on all content from “Chapter One” or filtering on all content across all chapters related to the “heart” or the “brain.”
This does not affect the actual availability of the chat. Availability settings must be set from the Availability Tab.
This is not available during the creation of the chat room and will only become available if you edit an existing chat room. You can also create the chat from within Content.
If you detach a chat from the Gradebook the assignment will still remain in the Gradebook but will be unattached. You will need to delete the Assignment from the Gradebook itself to fully remove it. See the Gradebook Help pages to learn more on how to do this.
