Hi I use the "add_object"-method of my Zope-Objects to send this mail. When generating a new instance it checks if a subscription Object with the adressee list is present. If yes then it sends the emails with <dtml-sendmail> to the list. In my navigation I have a subscribe/unsubscribe button, which enters/deletes the own email in the subscription object. Normally this applies only to Folders or folderish Objects. Hope this helps a little. Oliver Erlewein -- GMX - Die Kommunikationsplattform im Internet. http://www.gmx.net
