[Mediawiki-l] modifying header area / javascript question

[Chris Africa]

Hi Everyone. I'm new to mediawiki, and I'm not the site administrator,  
so I'm still feeling around for what I can do.

Today, I learned how to modify MediaWiki:Sidebar, MediaWiki:Common.css  
and MediaWiki:Common.js.

What I can't figure out how to do, after reading tons of  
documentation...
	1.	Utilize my javascript within my document. My <script> tag shows up  
as text in the body of the document, instead of executing the script.
	2.	Modify the top of the page to add additional common navigation,  
the way that I did with the Sidebar.

Maybe I just don't know what to search for, or what part of the  
documentation to look at. Can someone point me in the right direction?

Thanks!
