In world contact.

Understandably hiding SL names may not be your vision of your product, so maybe a suggestion, just to aid in cutting down the number of soliciting IMs some of us are getting.

I suggest some kind of indication on our profiles, whether it a badge, or simple traffic light type thing with a green or red light, just to voice whether or not we welcome contact in world. Maybe the toggle for it in settings so it isnt permanent.
