Generally, no. If you have a website then you can place a link to your facebook page on your website’s entry.
However, there are times when a Narnia resource can only be found on facebook. For instance: Facebook pages that have been created for a cast member. These are limited, however, to official pages only. They must be verifiable, and the person running the page must be honest.
No false Facebook pages will be added, and no role-playing character pages will be added.
