It's fairly common for folks, especially newbies, to post a page or upload an image file that they didn't really mean to -- testing something, or accidentally on the wrong wiki, or picked the wrong file.
Currently a regular visitor can't fully delete his/her own contributions, even seconds after adding it. This ends up leading to confusion, frustration, and burden on admins as the user tries to contact someone to get it deleted, or it just sits around until someone finds it.
It probably makes sense to allow a contributor to retract a new upload or page without requiring admin intervention, at least within some sensible time limit.
