Fiddling about on Google groups, I came across something which said:-
"The feeds below allow you to read new topics or new messages from this group with any feed reading software. When a regularly updated site (such as a Google Group) has a feed, people can subscribe to it using software to read syndicated content called a "newsreader." RSS and Atom are two formats for feeds. Most feed readers support both."
I'll have some of that I thought, downloaded one of the suggested readers (bottomfeeder), cut and pasted what I hoped was the URL for the feed
Perhaps not surprising as I have no idea what I am doing, but where did I go wrong and is it worth persevering?
