Just a thank you to everyone who has posted on this thread and added their contribution. It has been interesting and enlightening for me. One post suggested 5% male and 95% female. I find that unsurprising but a tad disappointing, although I did suggest 15% male in my OP.
I suppose I am at a slight advantage in that I have always been "into" IT and have used a keyboard for more years than I care to remember. Also 'Gransnet' does rather suggest a female demain and, in my view, if that is what is actually intended, it should be made clear in the "all are welcome" introduction.
I shall continue to loiter and observe and interject as and when I feel like it or feel it to be appropriate.
For the record, I have been male all my life (can I say that nowadays?
), 73 years old with two daughters in their late thirties and one grandson who is just 16 months old.
