G offered a wealth of wisdom, of great value to this group. I believe that his not being here is not his choice. I would be stunned to find that such a balanced and dedicated member did something "wrong". I am very unhappy that valuable threads started by him, and posts contributed by others to those threads are no longer available, let alone his posts to other's threads.
PPRuNe is very much the lesser for the loss of this contribution - perhaps it can be restored? If a heritage of a PPRuNe member's contribution can be erased in one action, is it worth the devotion of other contributors to create their own heritage of posts?
