Can someone please refresh my memory on the Millennium Kids.  I asked this before but can't find the thread now.

I am so confused by the following terms:

Millennium Kids
Millennium Girls
Millennium Boys
Millennium Teens
Millennium Kids Young Teens
Millennium Girls Pre Teen
Millennium Boys Pre Teen
Laura
Luke

Are any of these the same thing with just different names?  Exactly how many basic "Kid" packages does Daz have?

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
