The Website Manager allows you to add an external link page. To add an External link page, just create a new page and select ‘External Link’ radio button from ‘Choose the type of the web page’ page and click submit to load the following page.
This page can be changed to any of the available page types from the ‘Choose the type of web page’ page at a later time. The external link page allows you to add an external link to your website. When a visitor clicks the link he will be guided to the external link provided. You can either provide a Webpage address (URL) or an email address.
