owww, I really need this
a main profile and subprofiles for it, for pet owners, or a family and their child.
Please some one help us
Thanks
@dadvan & @bounomid,
Why wouldn’t a Group work for you? …much more convenient for those who have an entirely separate and secret family unbeknownst to everyone else. 
i actually need this for a social site for pet owners, so they can put their pets information like breed,age ets..
it is really big challenge for me, but i think brilliant idea 
i have basic knowledge of codes, hope someone can make this plugin
I nee this feature as well!! IS there a plugin or is the BP team working on this? It would be a godsend!! 🙂
you could sort of achieve that by making a multisite network where an member’s sites would be the sub-profiles but that may a bit of overkill.
