After a false start (apologies!), we are now on Facebook as a Community Page - Rotary Adelaide Light - just go to the website https://www.facebook.com/rotaryadelaidelight . 
You will be able to see the latest posts, but to do any more than that, you will need to have a Facebook account and login properly to Facebook.  Then you can "like" the page.  Once you have done that, any posts to Rotary Adelaide Light will automatically come up in your Facebook feed.
