  2. Select the watermark Position on the slide using the radio buttons.
  3. Set the Transparency percentage of the watermark from 0% (Opaque) to 100% (Transparent) on the Transparency scale.

  5. To open the web page in a new browser window, select Open link in a new browser window.

Password Protection

A password protects your course from unauthorized viewing. To view the course, the user will need to enter the password.

  1. Enable the option Protect presentation with a password.
  2. Enter the password in the Password and Confirm password fields.

Please note that the password is stored in the course in encrypted form. It can not be restored if you forget your password.

Time Restrictions

Users' ability to view the course can be limited by date. In this case, slides are only available in the specified time interval (before the date, after the date, between the dates).



To add a time limit:

  1. Select Display after or Display until.
  2. Select the date in the calendar that appears.

You can specify values in both fields at once to limit the time period in which the presentation will be available for viewing.

Domain Restriction

Allow users to view the course only from certain domains and their subdomains. The course can not be viewed on a local computer or another website. Use this option to protect the content from unauthorized distribution.

  1. Enable the option Allow playback in the following domains only.
  2. Enter the names of the domains from which you can view the course. Use a semicolon as the delimiter.

This option does not limit playback if you insert a course on a page on another domain using the HTML <object> tag.
