/**********************************************************
WPMU Cleanup
Original Version by Elad Salomons: http://www.ringofblogs.com/2008/06/10/wpmu-cleanup-script-to-delete-unused-blogs/
Modified by Boris Masis: http://www.borism.net/2008/12/31/deleting-inactive-wordpressmu-blogs
 
This script checks the WPMU database for blogs that have
not been updated for X days, then sends a notice to the
blogowner that the blog will be deleted after Y days.
 
It also automatically deletes blogs that have not been
updated for Y days, then sends an email to the blogowner.
 
On both occasions, the script will send a report with
details on warned and deleted blogs to the administrator.
 
This script has *NOT* been programmed as a plugin since
it is intended to be executed by a cronjob. As it is now
it should be run once every 7 days, but you can configure
it to do otherwise.
 
This script is *NOT* a final version and should be used
with caution and only if you know what you are doing. I
recommend testing it on a testsite rather than a livesite.
