[Mediawiki-l] Adding contents to the index page

[Washburn, Marshall P]

Hello,
My coworkers are converting a wiki from an old engine to one using mediawiki, and the users for this new wiki have requested that a save button be created at the top of the editing page, as well as the bottom, and to make there be an save page tab when editing pages. Which file(s) would I have to change or move code to for this to happen?

Thanks,
Marshall
