Thread:Project:Support desk/Create Post-date specific category

Hello,

My wiki, Ad Atticum, features syllabi and course outlines. I am trying to create a time-sensitive category from which I can retreive an rss feed to distribute each new syllabus added. The Special:RecentChanges page is to general because it includes all new pages on the wiki. How might I be able to create a namespace or category that will feature all new syllabi added within the span of a week, for example?

Thanks for any and all help.
