* Name: blackout
|
|
* Description: Blackout your ~friendica node during a given period
|
|
* License: MIT
|
|
* Version: 1.0

|
|
* About
|
|
* =====
|
|
*
|
|
* 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
|
|
* out they can't login again. That way you dear admin can double check
|
|
* the entered time periode and fix typos without having to hack the
|
|
* database directly.
|
|
*
|
|
* Requirements
|
|
* ============
|
|
*
|
|
* THIS ADDON REQUIRES PHP VERSION 5.3 OR HIGHER.
