Sorry, I haven't been ignoring your responses to this thread.  I've
been having problems with the DNS servers, I never received your post
Chris at https://mail.gna.org/public/relax-devel/2006-10/msg00133.html
(Message-id: <1161682551.7703.107.camel@mrspell>) or your post Seb at
https://mail.gna.org/public/relax-devel/2006-10/msg00134.html
(Message-id: <453E1E41.7060500@xxxxxxxxx>).  I think that the DNS
servers behind the address nmr-relax.com will need to be changed.  I
might start a new post about this later.  I think my copies of these
two posts are still sitting on a dead ZoneEdit server!  I might get
them one day soon.
