What about this idea:
We can flesh out profiles with Data, demographics, and contact info. No one cares about it, so we leave it off.
We can also customize it by a list of names that are connected, for those that have registrants
So 2 options: throw the demo info up on each, giving some unique content.
and or
Throw up member first names last init of those registered in them, then only index them if they have members?
However, 80% of our traffic comes from these "duplicate" pages.
