-------- DESCRIPTION  
---------------------------------------------------------

Simplenews publishes and sends newsletters. When subscribing to a Simplenews

user's e-mail address on the confirmation page. Further, due to the absence
of a noindex tag, the list of e-mail addresses can subsequently be indexed by
search engines.
