Export extended profile data to useable format

Hi All

I need to be able to export extended profile data to a csv format from a BP installation.
I have tried to use the existing plugins, but they only export base profile fields and some other fields I dont have active.

Is there any way to do this that you know of?
Also, when a user registers on one of my sites, they only get added as a user to the network and not to the site they have registered on. Then when I want to do a user search as admin, I have to search through the whole network. Is there a way to add users to a site automatically when they register on that specific site?

Thanks!
