This is really sad to hear, like many Bill was a massive part of the forum when I joined which was around 15 years ago now. He was one of those few special members that seemed to be part of the fabric of the place, as @c1982 said I remember he had the TT Emergency Board so that we could keep booting off about Everton if this place ever went down - I think that shows the work he put in behind the scenes. The fire that he showed in his posting was no doubt from a deep love of Everton and as others have said, not necessarily a bad thing at all.
Hoping that Bill is at peace, condolences to his family and of course @patto.
