Advanced archiving

… or something like that! 🙂

I’m using a two-column style layout, and in the narrow one I have a list of top movies;

Top Movies
1. Movie 1
2. Movie 2
3. Movie 3

As it is now, I enter these by hand, in other words, I write the code. Is there a way I could use some plugin to help me display this?
Further more, I’d really need to find a way to keep an archive of these top lists, since they will be changed weekly. That archive should also be viewable online, by a normal user.

I don’t know how to do this, so I’m asking you for help.

Thank you,
Ivan.
