I want to have page on my site with a list of lectures. each list item should be a link to the specific lecture. When a story in that category is added, the list should be update too.

for example:

Category: lectures
items:
- Su 10-12-2003 morning
- Su 10-12-2003 afternoon
- Su 17-12-2003 morning
- Su 17-12-2003 afternoon

And the lecture should be at: mysite/lectures/10-12-2003mo

Is it possible that there is somebody (who writes the lecture) adds a lecture and that the list get updated to? And how do i make such a list?
