Hi, Undoer is a product/patch that enables transactions to be undone based on a date. Useful if you or someone else has managed to make a lot of separate changes that would be cumbersome to undo the usual Zope way and no recent (enough) backups are available. See the Undo tab in the Zope Management Interface for instructions on how to use it. Get it at http://products.nidelven-it.no/undoer -Morten
