Dupla web site
After George Booth's suggestion to try getting information from
www.dupla.com, I have been repeatedly unable to get anything other than
their welcoming message (in German and English), followed by an invitation
to explore several following web pages. On both of my browsers, both the
German and English pages which are supposed to follow are completely blank!
Can anyone else access this site? Surely this does not reflect upon their
current state of research ...
