You can add hyperlinks to your comments in the class blog by using a bit of html code. You might want to use a Hyperlink to an online article or a reference. Alternatively, if you want to add a video of your training, you will need to first set the share permissions on your video and then add the URL link to a piece of code.
Look at the slide deck on the right to see how and click on the button below to access our class blog.
