+A GNU social node can be configured as "private", which means it will not
+federate with other nodes in the network. It is not a recommended method
+of using GNU social and we cannot at the current state of development
+guarantee that there are no leaks (what a public network sees as features,
+private sites will likely see as bugs).
+
+Private nodes are however an easy way to easily setup collaboration and
+image sharing within a workgroup or a smaller community where federation
+is not a desired feature. Also, it is possible to change this setting and
+instantly gain full federation features.
+
+Access to file attachments can also be restricted to logged-in users only:
+
+1. Add a directory outside the web root where your file uploads will be
+ stored. Use this command as an initial guideline to create it:
+
+ mkdir /var/www/gnusocial-files
+
+2. Make the file uploads directory writeable by the web server. An
+ insecure way to do this is (to do it properly, read up on UNIX file
+ permissions and configure your webserver accordingly):
+
+ chmod a+x /var/www/gnusocial-files
