DCM Desktop Content Manager is a separate component that allows you to edit Joomla articles from a standalone application for Windows systems. This way You will be able to correct any material without entering actually in the site itself.
DCM Desktop Content Manager

This extension is a new way to edit content based on Joomla and K2, the work is done through a special application on your desktop. In addition, instead of the built-in editor, you can edit the content using a separate HTML editor or any other of your choice – suitable for WinWord and Livewriter, Notepad++.
The component consists of two parts and is suitable for Joomla versions 2.5 and 3.1 installed on a Joomla site and a separate application for the computer that will receive the contents of the webserivce project where You will be able to manage their own content. The extension has many features that will make managing content much easier.
Note:
I was able to install the component and configure it for your website running Joomla 2.5, but for some reason, display materials, and it is not entirely correct. Perhaps this component is not yet fully finalized, but the idea is interesting – You can set a password to transfer content managers site management.
