How do you stop your date of birth and other details from being shown on Salamyou. Second, although there is an option that allows us to choose who we want to see our posts from 'everyone, friends, friends of friends' etc, it doesn't remain that way permanently. Every time we log on the 'everyone' option is always there. I realise one reason this is so because we may want to change preferences later, but even when I set it to 'friends', I have received messages from those outside my list. If we restrict it to 'friends', can it not remain that way until we set it otherwise even after we log out.
