how can I refer to Geni persons or family trees

I am doing a wider search on a group of people.
Sometimes there is information on Geni.
But it is not easy to make e simple reference to a specific person.
Yes I can copy the URL, but that is ugly, i.e.
- Poen Hauw Oei
- www.geni.com/people/Poen-Hauw-Oei/ is not working
- neither is there a number (personal ID or so)
- nor something to indicate a family tree.

Any suggestions
And I cannot reach the Geni organizations!
