Yes Marcus, that's right.
Namrata, if students follow a teacher, they will get weekly updates on the public learning objects (tests, tutorials, classes) created on WiZiQ by that teacher. They would not need to change settings to activate it. However, if they do not want to receive further notifications, they can simply deactivate them by going to their mail notification settings.
Yes George, the updates will be aggregated in a weekly notification but it will not contain forum posts yet. Let's see how soon we can include discussions too.
