[Mediawiki-l] Restricting random page from certin namespaces

[shardsofmetal]

I was wondering if it is possible to restrict the random page feature from 
going to certain namespace pages. Also, I don't know if it already only goes 
to pages in the main namespace. If so, can I make a special link for a 
random page for a certain namespace. For example, "Random article", "Random 
talk page", etc. Thank you for any help you can give me, Shardsofmetal
