I use Skype all the time to talk to my sister who lives in England. I do not have a camera attached to my computer, but my microphone and chat feature work just fine. Search for my Skype name: kriddlec. :)
All of my sisters refuse to turn on their cameras when we are on Skype because I don't have a camera and they think it is unfair! Talk about Skype connecting families; last week I was on Skype with my sister Velecia. I sent her links at which to look, we watched Youtube videos "together" (shared links and pushed play at the same time), etc. We were both giggling over how fun it was.
