If you don't want everyone to be able to see your View, but you would like to show it to a few people who are not registered with Mahara, then you can make your View visible to the public through a Secret URL. This is a special link which is difficult to guess. You can let others know about your View by sending them the link.
Click Add Secret URL. The URL will be shown in the right hand pane. You can then share it by copying and pasting it into an email. Add dates to the From/To boxes if you only want the view to be accessible for a specific time period.
