Deleting not used wiki pages

I created a wiki page as TW/Main_Page for zh-TW, but I found out that in ISO
639 code "TW" has standed for a language called "Twi".

So I created a ZH-HANT/Main_Page to present "Chinese - using Traditional Han
characters" to replace the old one this morning; however, I searched the
openoffice wiki page
http://wiki.services.openoffice.org/wiki/Languagesusing zh-TW, and I
change ZH-HANT/Main_Page into ZH-TW to keep
the consistence with OpenOffice.

As a result, there are two unused wiki pages and categories "TW" and
"ZH-HANT" (Oops! :P). I would like to ask the one who can delete unused wiki
pages to clean both of them. Thanks in advance.
