+TestDrive
+=========
+
+
+Testdrive is a Friendica plugin which implements automatic account expiration so that a site may be used as a public
+test bed. 
+
+When an account is created on the site, it is given a hard expiration date of 
+
+
+$a->config['testdrive']['expiredays'] = 30;
+
+Set this in your .htconfig.php file to allow a 30 day test drive period. By default no expiration period is defined 
+in case the plugin is activated accidentally. 
+
+
+There is no opportunity to extend an expired account using this plugin. Expiration is final. Other plugins may be created
+which charge for service and extend the expiration as long as a balance is maintained. This plugin is purely for creating
+a limited use test site. 
+
+An email warning will be sent out approximately five days before the expiration occurs. Once it occurs logins and many 
+system functions are disabled. Five days later the account is removed completely.
