Using the Regional section will get you close to that. I've been adding every person from NorCal and some others to my Buddy List as they pop up. I've got a pretty sizable population of Teneres within a hundred mile radius. It does take time and a lot of reading. Checking out every introduction as it's made, and the history, will speed things up. Now watch, somebody has a better way... ::024::
I haven't found a way yet, but it would be nice to be able to send a BBQ, or RTE invite to everybody on the list at one time.
