To leave a comment, either click within a paragraph and select the letter c, or else just double-tap within a paragraph.

A box will pop up in which you can enter your comment. Once you have done so, click “Submit comment.” A comment bubble will appear at the end of the paragraph, containing a number to indicate how many comments have been made on that paragraph.

If you wish to respond to a comment that has previously been made, just click or touch the relevant comment bubble and enter your response. Then click “Submit comment.” The number in the comment bubble will increase by one to indicate how many comments have been left there.

Gold and Platinum Members will automatically be notified when someone leaves a comment.

You can do any of the following:

• Press the Escape key.
• Tap or click again on the comment bubble.
• Double-tap on the comment box.
