There is an intention to notify editors if more than thirty edits have happened to the article and therefore their rating has expired. How will this be done? Will it be by bot message to your talkpage or will a note appear on your screen when you next visit that article? If the former I think we will need a way to switch that off so that individual editors can opt out.

It's just a note on the page, inside the article feedback tool. It shows your old ratings and says that they've expired. If you think that they're still the right ratings, then all you need to do is to click "Submit" again.
