I think.....we have to re-read our good Ed's response again, as like you I read it as being that she responds to ALL emails as long as they aren't rude or aggressive. After looking at it again though I think we have to realise that it's got to be impossible for her to answer every single email she receives- she just answers a few.
It would appear that your emails and ones I've sent to her in the past were, shall we say overlooked maybe????
i'm hoping it's that anyway and the silence we've been treated with isn't anything sinister, lol. ;-)
