Noobie Question: Sub-profiles

Hi

I have just completed my install of version 6. I have run 5, but at the time it did not suit my needs.

I am wondering if there are mods or if it is possible to have linked sub profiles. Like if Mama bear wanted to create profiles that were linked to her primary account that she created and maintained and had rights to, was linked to hers but the little cub or papa bear could log in.

I hope that makes sense. How you like my puck?
