Show most recently updated post at top

Hi all,

I’m using the P2 theme in a site I’m running, and am looking for a way to show the most recently updated post at the top. So, whether that’s an edit on a previous post, or a comment on a previous post – I would like those to bubble up to the top.

Does anyone know of a relatively straightforward way to do this?

Thank you!
