+co-administrators
+-----------------
+It is possible to allow other people to upload and manage
+pictures/descriptions. In admin interface, select "Add an co-administrator"
+and fill informations (user name and password). Then, you need to communicate
+to your user its username and password. He/She will be able to modify this
+password afterward. Only admin can add new users.
+
+Other co-administrators will be able to add markers, and delete/modifiy them.
+They cannot modify markers they have not created. admin is the only user
+allowed to manage markers of other users. If you plan to have several
+co-administrators, you may want to create a normal user for yourself, and use
+it to manage your markers. You will then only use admin account when really
+needed.
