For any piece of content it is possible to decide whether or not it should be made immediately available to students or not. One of the advantages of this is that you can prepare content in advance and set it to be automatically released to students at a time that is appropriate. To do this:
1. When adding any new piece of content you are given a page of options. (If the content already exists edit the content)
2. One of the options is to Permit Users to View this Content. To ensure the item is available make sure the Yes option is selected.
3. If you want to set availability based on dates fill in the dates and times in the below boxes. (For example: this could be useful for setting up a test).
