Discussion Page Tutorial
From Linked Earth Wiki
The LinkedEarth wiki supports talk pages (also know as discussion pages). A discussion page is a page which editors can use to discuss improvements to the LinkedEarth ontology or to an article on the wiki. When viewing a page on the LinkedEarth wiki, a link to the corresponding discussion page appears on the "Discussion" tab at the tops of the page. Click this tab to switch to the discussion page.
User pages also have associated discussion pages (for example, User_talk:Khider). When the LinkedEarth team and other editors need to contact you, they can leave you a message on your talk page.
