After a google there appears to be loads. Can you recommend one please?

I was not really posting it as "news" - merely a topic of potential interest :-)

Are postings like this appropriate for this list? Or are most folks
here scanning the various floss sites regularly in any case? I have
perhaps 25 RSS feeds to keep me going! lol. I don't read them all
mind. A few people seem to have found it interesting........

Thanks for that. Book-marked for a read at some point. :-)

Whilst I am interested in it and I do use gnuPG from time to time, I
