So fed up.
I don't know if anyone else checks their security on LinkedIn - but I set up a fake profile to check security and realised that everything is visible, despite it being on the highest security settings. I'm cross because a lot of the stuff I have done in the past, though very pertinent, won't be seen as such by the new 'customers' I am targeting.
So, I deleted the account and started again. This was a total pain as I had to reconnect with everyone and rejoin groups. Guess what? Same thing happened.
