Go to Management Pages section and select Prepared Emails:

Figure 4.92. Management Pages: Prepared Email

From the Prepared Emails page, select the template you wish to edit by using the Edit link. You will probably have 3 pages of templates, not just 1.

Figure 4.93. List of Prepared Emails

Make your changes to the selected template. Avoid changing any of the embedded program variables (anything that looks like {$this}) however, as these will dynamically generate appropriate information. (For example, {$reviewerName} in the figure below will insert the Reviewer recipient's name into the email.) Remember to Save your changes.
