Raymond Danks <ray.danks@se-eng.com> hasn't contributed any changes to
meta-virtualization since 2012 and is listed on Linkedin as no longer
with Sage Electronics since March 2013, having moved to a completely
different profession (firefighting). So it is almost certain the
listed E-mail address is invalid and has been for a long time.
