[xwiki-users] publication dates in articles

Dear friends, I request help on a few changes that we are making to our internal XWiki installation. We run XWiki 1.7 over a tomcat 6.0.18 & mysql 5 installation. I see that the blog application has publication date feature which I believe runs as a scheduled job. Is there a possibility to add publication date to a page created in any other space. On the face of it, pages created in both blog space or any other space appear to be the same. So there should be some possibility that we can add scheduled publication dates to pages without making major changes to the present XWiki installation. Also, can we extend the category & sub category feature to any page outside the Blog space. Any help on this would be greatly appreciated. Also, if I may suggest a name for the new skin, I would suggest 'sparrow'. It kind of rhymes with 'arrow' & the bird is small, light & even the colors seem to match. Thank you all...
