If anyone still wants to play, try it like this. Using the left mouse button, highlight Eleanor’s name and let up on the mouse button. The box that pops up (very briefly) is a rectangle, maybe one inch high and two inches wide. The words in this box are “Text: Eleanor of Aquitaine”. An inner box (green) says “Person Actions”.
When I click on the green box, a popup pops up. “Hi auntiepam” in the upper right corner. Eleanor’s name in large text at the top, and the words “Person Action”. The options are Find profile on Facebook, Find person on Google, Find blog on Technorati, and Find photo on Flickr. When I click those options, it gives me a list of possible Eleanors.
Oh, and it worked with Johnny L.A. too.
I haven’t added them as Doper Friends, so there’s nothing special about them (outside of their innate specialness, of course).
ETA: Remember this is highlighting in regular text, not highlighting or clicking like you do to check e-mail and PMs.
