This is a subscription service to be automatically notified by e-mail when topics change in this '''LangWiki'''  web. This is a convenient service, so you do not have to come back and  check all the time if something has changed. To subscribe, please add a  bullet with your [[http://svn.mrc-cbu.cam.ac.uk/twiki/bin/view/TWiki/WikiName|WikiName]] in alphabetical order to this list:

 * [[http://svn.mrc-cbu.cam.ac.uk/twiki/bin/view/LangWiki/TWikiGuest|TWikiGuest]] - example@your.company

=== Web Changes Notification Service ===
Each TWiki web has an automatic e-mail notification service that sends  you an e-mail with links to all of the topics modified since the last  alert.

Subscribers are listed in WebNotify following one of these bullet list formats:

''three spaces'' * [ ''webname'' . ] ''wikiName'' - ''SMTP mail address''
 ''three spaces'' * [ ''webName'' . ] ''wikiName''
 ''three spaces'' * ''SMTP mail address''
 ''three spaces'' * ''SMTP mail address'' : ''topics''
 ''three spaces'' * [ ''webname'' . ] ''wikiName'' : ''topics''

where ''topics'' is a space-separated list of topic names.

 * Specify topics without a ''Web.'' prefix
 * Topics must exist in this web.
 * Topics may be specified using * wildcards
 * Each topic may optionally be followed by an integer in  parentheses, indicating the depth of the tree of children below that  topic. Changes in all these children will be detected and reported along  with changes to the topic itself. ''Note'' This uses the TWiki "Topic parent" feature.
 * Each topic may optionally be preceded by a '+' or '-' sign.  The '+' sign means "subscribe to this topic" (the same as not putting  anything). The '-' sign means "don't send notifications regarding this  topic". This allows users to elect to filter out changes to certain  topics (and their children, to an arbitrary depth). Topic filters ('-')  take precedence over topic includes ('+').

For example:

{{{
   * daisy@flowers.com
   * daisy@flowers.com: Web*
   * TWiki.DaisyCutter: Petal* (1) TWiki.WeedKillers (3) Red*Phlox
   * TWiki.StarTrekFan: * - *Wars - *sInTheirEyes - *shipTroopers
}}}
A user may be listed many times in the WebNotify topic. Where a user has  several lines in WebNotify that all match the same topic, they will  only be notified of changes to that topic ''once''.

If a ''TWiki group'' is listed for notification, the group will be recursively expanded to the e-mail addresses of all members.

'''''Tip:''''' List names in alphabetical order to make it easier to find the names.

'''''Note for System Administrators:''''' Notification is supported by an add-on to the TWiki kernel called the MailerContrib. See the [[http://svn.mrc-cbu.cam.ac.uk/twiki/bin/view/TWiki/MailerContrib|MailerContrib]] topic for details of how to set up this service.
