Well, I see the Paul McGann 'Big Finish' audios as being canon, plus the books featuring the Eighth Doctor. The Paul McGann 'BF' audios and books must be canon, cos in 'The Night of the Doctor', the Eighth Doctor mentions Lucie Miller, and she was in the Audios. Other than them, I don't see anything as canon, other than the TV episodes.
There really is no point in trying to get anyone to discuss this. As someone else said earlier, it will only cause arguments to happen, and you dont want that, do you?
