Hmm, sometimes one is not quite logged in, as witnessed by an absence of ‘Club Member’ beside ones Forum name, but still with a tick on the avatar.
However, go the Home page where it now agrees one is not logged in (from previously ghosting on Forum without ‘Club Member’), and login there to return the ‘Club Member’ while on the Forum even though no logout performed anywhere.
I guess there is a confusion here between Forum Member and Club Member. I suspect Forum membership is maintained through the cookies, but Club needs a login. No doubt others know better than I how it all works.
