Antonio asks:
But i find no way to view all *content* of these pages
[in a category] in 1 page...
The extension
http://www.mediawiki.org/wiki/Extension:DynamicPageList_%28third-party%29
lets you write something like this:
<dpl>
category=MyCD
include=*
</dpl>
to produce a page with all the content from all pages.
