RC2 & MSN Premium

Why are we at RC2 and still MSN Premium is not compatible!? This is a
Microsoft product, one that I would think is pretty important in that it
works with Vista, and I still cannot fully use Vista because we use MSN
Premium for the Parental Controls it offers. I have looked at the Parental
Controls built into Vista which do look promising, but one key feature is not
there that is in MSN Premium, and that is the ability to limit my 9 year old
daughters e-mail box from getting mail from those who are not in her contact
list. This is a must for me, because I do not want my daughter opening up
all the porn spam that always tends to find a way to our boxes.

Is this feature going to be available in Vista?

I know there is a Live Parental Controls that is in Beta and they have said
this is something coming, but that has been the story for months now.
