At the time of the rumours in 2007 I was one of the mods on this forum's predecessor, and as such I was party to certain information which, at the time, I was duty bound not to pass on. Seeing as so much time has now passed, I guess it doesn't matter if I share what I know, although I won't name names.
One of my fellow mods at the time had a private meeting with a very well respected director of the club at the time, and was told by this person in no uncertain terms that the board had indeed met with people representing, or at least claiming to represent Paul Allen, and that there was a genuine, serious interest there.
Make of that what you will.
