Export articles in demo mode

KBPublisher ascribes the "try before you buy" philosophy. 

You can try the export plugin by using a key of demo key instead of a purchased key.
This allows you to set up, create and test the export plugin and to work out if you want to buy it.

There are some limitations with the demo model:

• Only the first three articles for each category will be exported.
• A watermark is added to the page background.
