It's good to know there are different communication methods available.

As for me, I have a headset (has mic) but no webcam so that's good to hear that is also acceptable.

Hmm, I guess I have to Google+ enable my Profile?

If I do that, are there any privacy concerns I need to be aware of or address?

I tried reading some of the help pages and it seems OK but ...

I tend to be very cautious with being "Public" ;)
