+# Patch for email notification on page changes T.Gries/M.Arndt 11.09.2004
+#
+# This new module processes the email notifications when the current page is changed.
+# It looks up the table watchlist to find out which users are watching that page.
+#
+# The current implementation sends independent emails to each watching user for the following reason:
+#
+# - Each watching user will be notified about the page edit time expressed in his/her local time (UTC is shown additionally).
+# To achieve this, we need to find the individual timeoffset of each watching user from the preferences..
+#
+# Suggested improvement to slack down the number of sent emails:
+# We could think of sending out bulk mails (bcc:user1,user2...) for all these users having the same timeoffset in their preferences.
+#
+# - Visit the documentation pages under http://meta.wikipedia.com/Enotif
