To create a dedicated reviews page follow these instructions:
Create a page in your CMS or store that would normally contain any kind of content.
Add an All Reviews widget to your Fera account (see GIF below)
Under the first tab, Location on Page, click 'Change' and choose 'HTML Tag Mode'.
Copy the HTML tag it gives you.
Edit your CMS custom page using the HTML mode (not the WYSIWYG mode) and insert the tag you copied in step 4.
In the widget editor back in Fera, click the Refresh icon on the preview browser window.
