+This plugin will allow you to enter a date/time periode during which
+all your ~friendica visitors from the web will be redirected to a page
+you can configure in the admin panel as well.
+
+Calls to the API and the communication with other ~friendica nodes is
+not effected from this plugin.
+
+If you enter a period the current date would be affected none of the
+currently logged in users will be effected as well. But if they log

+the entered time periode and fix typos without having to hack the
+database directly.
