cross referenceing links

I create a link in a new page. Let's call the origingating page JOE (in the PEOPLE catagory) and the link in it KAREN. Obviously I can look up JOE in the Search box, but even after I have clicked on the KAREN? reference and added info the particular entry has no TITLE, so 1. I can't look it up in the Search box, and 2. It doesn't fall under my catagory of PEOPLE, and 3. I can't later create a link in SALLY's page that references KAREN. How the heck do you cross reference? Is this the same as LINKBACK and when will that be ready? I read somewhere that linkbacks is now opperational, but the reference in the FAQs page is empty... Thanks!
