The CoS will never disclose its members' details - unless we are legally obliged to do so, in which case we will gladly comply with the law.

Otherwise, it's down to your own discretion to whom you diclose personal information to - just as in any other matters.

I've never met anyone in the CoS yet who would wilfully "out" someone they knew wished to keep their affiliation private.
Human beings are as significant as a cigarette burn in the sun.
