Without Trace

I wonder if anyone has experienced as I have the sudden disappearance of a dear friend on the Club site, I personally have had friends whom I got on really well with and in some cases helped nurse them through a bad patch which they were going through, or asking my advice on something personal then suddenly completely off the radar without any warning. Could it be that their secret is no longer secret or maybe even fallen victim to some illness,It would be nice of them ,if possible , to let us know why they were missing. I do wish them all the very best of luck wherever they are.
