 Conditional activities are simply to set up now in Moodle 2.7 and you can use all conditions to restrict access. If your access criteria are more complex, you can use a set of nested restrictions to achieve what you need. So, here's a standard forum where students have to introduce themselves at the start of a course and we're going to restrict access so they must first either read the course announcements or wait until June 10th. So, if we scroll down and look at Restrict Access, there's a new button Add Restriction and when we click it, we're presented with a variety of restrictions. Activity completion, date, grade, group, user profile fields and restrictions set. You choose this last one if you had more complex criteria for nested restrictions. Let's first click Activity Completion. The setup screen is much more streamlined as we select course announcements as our first condition. And then to add the second restriction, we click the button again and choose date and select the date after which all the students must access this forum. We can select either all or any of the restrictions and choosing any then gives us the or condition. To hide the forum completely on the course page we click the i. If the i is open then students will see a message telling them what to do to access the forum. So, let's save and return to course and then we can see how this is displayed.
