I have decided to offer the different Creative Commons licenses as an option on Internet-Encyclopedia and have changed the notice at the bottom of the page to this:
"gnunote" => "Unless some other copyright license such as one of the <a href='http://creativecommons.org/licenses/'>Creative Commons licenses</a> has been selected by the original author of an article all text is available under the terms of the <a href='http://www.internet-encyclopedia.org/wiki.phtml?title=GNU_Free_Documentati on_License'>GNU Free Documentation License</a>. Use of images may be restricted, check the description of the image for details.
This should allow the use of the Public Library of Science articles and material available under any other licence including material available only for non-profit use or otherwise restricted available for use.
As to whether Wikipedia should make a similar change...
