Telecross with the Red Cross for four years before I went to live in the USA.
Signed up to start again now I am back in Aust.

What did I get out of it? I got to share a little time (over the phone) with some wonderful people each morning that I would never have met otherwise.

Its a great service. Here is the blurb from the NSW division that I volunteered with for the first four years.
