NP Sir
Also just like to say at the moment all the major Social Media Websites are changing at a dramatic rate and not all functions are the same on all devices/accounts.
One thing to be aware of is face recognition I can't recall if Facebook kept using as many were complaing as rolled out across the world* This would search the world of Facebook for pictures of people (a bit of a in a nutshell explanation)
A few months ago a test work account with a few simple pictures of me and others but with no mention of external emails,contact details or names then very quickly had our friends and family seeing these test accounts as suggested friends the only link was the photos!!
*Please note Facebook will test on a small percentage of devices certain ideas, formats and options these small amounts can be tens of millions sometimes some of the ideas are not always very well announced to a non techy audience so do pay attention in case something looks different on the screen...
There are ways if not paying attention to end up with people seeing public classified statuses and public classified posts by subscribing!! You possibly don't get notified very clearly who is subscribing to this if you set it up.
Many of the new groups, levels of access and options im sure many don't really compute what they mean if they don't have at least a background in I.T.
