Each netfrag.org web does an automatic email notification of recent changes. Users can subscribe / unsubscribe themselves in WebNotify of each TWiki web. The Perl script mailnotify is called by a deamon in regular intervals. The script is sending an automated email to subscribed users in case some topics changed in a web within this interval.

Implementation note: Edit the cron table so that mailnotify is called in an interval of your choice. Please consult man crontab of how to modify the table that schedules program execution at certain intervals. Example:

% crontab -e
15,45 * * * * (cd ~twiki/public_html/bin; ./mailnotify)
