Sean has been struggling with "the illness which shall not be named" - the Lord Voldemort of health problems perhaps. I suspect that, as people aren't coming back with anything, Sean is probably playing his cards close to his chest right now. We are of course all crossing fingers and more for him.
Sean, if you are still monitoring our posts, I am sending you my sincere best wishes. You are in my thoughts and I hope you can cope with your problems.
