Put

in a page.

After seven days, the page will have a nice box at the top saying "The information on this page may be out of date", and watchers of the page will receive an email notification that the page needs to be updated.

This is best done as a plugin combo: a macro and a service. Which means we'll need to add services to Confluence.

Suggested by Micheal Taylor on the confluence-users list:

"We are thinking of switching to Confluence from Twiki. One thing that seems to be missing is notification for out-of-date pages. We use this heavily in Twiki. When you edit a page, you get a few radio buttons at the bottom of the edit page where you can select how long a page is valid for before it becomes out-of-date (a week, a month, a year, etc).

When a user visits an out-of-date page, there is a warning at the top that the page may be out-of-date. As well, the last editor of the page receives an email periodically saying which pages are out-of-date.

We would miss this sorely if we went to confluence. I would probably have to write some sort of replacement of my own.

Does anything like this exist in Confluence?"
