Thanks.
Well for the curious.
One PM from over 2 years ago from guy with German e-mail address hence broken English and bad translationasking for details about a photo Kiwi posted.
One PM from about 3 months ago from guy who has entered a full postal address, signed up several years ago that looks like a genuine home in Australia and PM started with G'day. Asking about a copy of an article Kiwi mentioned he had and could PM to someone else.
One recent from a South African who had been a member for a while, reasonable address entered and asking about same pdf.
I would say they were all OK and have suggested to Kiwi a way to share the PDF without giving any of his details (advantage of waiting for new forum software).
With this forum being up in the top rankings for this type of subject if anyone around the world happens to do a google search for the items in question first results are posts on this forum so that is what has likely drawn them here if they have a problem with their similar machines.
