How do I create a link to another web page?

You can add links pretty much anywhere that you can add formatted text, e.g. at the top of categories, in product descriptions and on info pages. While editing your text, select the text you wish to link in the editor and then click the link icon as shown below.

You will then be prompted for the link.

You can also add links to the images that appear on content Pages. Follow the usual steps to upload or edit an image and then enter the link when prompted.
