The About tab appears on every personal, organisation and project page. On personal pages it displays information about yourself and the pages you like. On organisation and project pages it displays relevant information and contact details and links to partners, donors and supporters and beneficiaries. The page manager needs to provide some description text for the page but the rest of the details are optional, so they will only appear to page visitors if the manager has included the information. You can also share documents and show the relationship between your page and other pages (help on editing these relationships is given here).
