I signed in my wife as a Skype member and started the chat on her user account. Then I set up myself as a contact on her user account and had her contact me. I received her message on my iPod Touch and relayed a message. FREE!! No more cell phones.
I don't need to buy a wifi phone either. I was looking frantically for one, to replace my cell phone service (which I just cancelled YEAH!). But once I set up the chat relay, I realized I didn't need one. No need to carry around yet another device.
Chat works fine for letting your honey know that "I'm Ok" "Coming home soon" "What's for dinner" etc.
Be sure to check each person as "online" in the status menu. What I did to set up the relay was to sign in as me, make sure i'm "online", then sign in as her, check her as "online" and set up the chat.
You can only chat if both are members of Skype and both are online at the same time.
