+Public Server
+=============
+
+
+Public Server is a Friendica plugin which implements automatic account & post expiration so that a site may be used as a public
+test bed with reduced data retention. 
+
+This is a modified version of the testdrive plugin, DO NOT ACTIVATE AT THE SAME TIME AS THE TESTDRIVE PLUGIN.
+
+//When an account is created on the site, it is given a hard expiration date of 
+$a->config['public_server']['expiredays'] = 30;
+//Set the default days for posts to expire here
+$a->config['public_server']['expireposts'] = 30;
+//Remove users who have never logged in after nologin days
+$a->config['public_server']['nologin'] = 30;
+//Remove users who last logged in over flagusers days ago
+$a->config['public_server']['flagusers'] = 146;
+//For users who last logged in over flagposts days ago set post expiry days to flagpostsexpire
+$a->config['public_server']['flagposts'] = 90;
+$a->config['public_server']['flagpostsexpire'] = 146;
+
+Set these in your .htconfig.php file. By default nothing is defined in case the plugin is activated accidentally. 
+They can be ommitted or set to 0 to disable each option.
+The default values are those used by friendica.eu, change these as desired.
+
+The expiration date is updated when the user logs in.
+
+An email warning will be sent out approximately five days before the expiration occurs. Five days later the account is removed completely.
