Hello; There is a paragraph on how to create a special page in the FAQ
http://meta.wikimedia.org/wiki/Meta:FAQ#How_do_I_add_my_own_dynamic_content_...
It's not so difficult. At the end,it says you have to create a simple page and write the name of your special page in it. If you forget this the title of your special page will have < and > around. I haven't got a clue why creating a page with the name in it solves this, but it works
Hope this helps
