Ah, you should have said so earlier.  See MediaWiki's own page [1]  
for the full story. You could try using CSS to instruct the web  
browser to select a scriptlike font.  I believe Wikipedia's policy  
[2] is to use wikitext or HTML to render math unless it's only  
possible with LaTeX.  This way the page remains machine-readable  
(sort of).  So something like

<span style="font-family: 'zapf chancery', cursive;">W</span>

should work.  You can make that a template to avoid code repetition.

Yes, there's got to be a way.  The sure-fire way would be to search  
the MediaWiki source code.  The way these math-on-the web programs  
work is they take text, write it into a file, then run (la)tex on the  
file.   The temporary file needs a preamble, so if you find where  
it's written you can just update that preamble.  Whoever wrote this  
particular extension to MW may have built in some customization  
mechanism that would do this for you, but I don't know.

Judging on your next paragraph, however, I think your best bet is a  
solution within the current MW configuration.

In the olden days this was the only way to use tex.  Look at the TUG  
site (see "more links" at the end of the message) for information on  
that.

Hope that helps!
