[Mediawiki-l] Tweaking Random Articles Button in Monobook

[Ekompute .info]

Hi, I am practically the sole writer of my wiki at
Dummipedia<http://www.dummipedia.org/Main_Page>.
As I have quite a few articles that are in various stages of completion, I
would like to hide these articles from viewers when they press the Random
Articles Button in the left panel. To differentiate between completed
articles and incomplete articles, I page-protect all complete articles
against possible vandalism. How do I tweak my Random Articles Button so that
only protected articles will be displayed?

Thank you for your kind assistance.
