Thanks for drawing security to our attention Wendy. I'm exploring what happens if posts are shared on Facebook and Twitter, and particularly where it will be shared on Facebook.
Of course anyone who posts medical and personal details here is sharing them on the internet and you have absolutely no knowledge at all as to who has joined the forum and therefore who is reading your personal stuff. I used to think rather innocently that it was just us, and our supporters but then went to business meetings where posts were discussed by employees in the charitable sector, health sector, etc. and I was rather relieved I hadn't put up anything I'd have preferred to keep to myself and my close acquaintenances.
Here goes. Posting, and will share with Twitter and Facebook and view the consequences.
