The Dragontalk project provides a set of extensions for the [http://www.mozilla.org/ Mozilla] products
[http://www.mozilla.com/thunderbird/ Thunderbird] (email client) and 
[http://www.mozilla.com/firefox/ Firefox] (web browser).

One of the goals was to get information about the user's operations. For instance, if the user
sends or replies to an email, Dragontalk sends a !SendEmail or a !ReplyToEmail event to some TCP port
on localhost where an XMLRPC listener can catch it. For the browser plugin, notifications are sent when
browsing the web. In concert with other programs that implement the listener part, we use this to elicit
the user's context - see the [http://usercontext.opendfki.de/ User Context] project.
Of course the user can disable the plugins at any time.

Apart from these event notification plugins, there are Thunderbird plugins that
provide other functionality such as mail classification and quick opening of
folders using autocompletion.

The Dragontalk extensions were developed in the [http://www3.dfki.uni-kl.de/epos/ EPOS] project and
are used in the [http://www.dfki.de/mymory Mymory] project, too.
