I am interested to know what goes on on the Skype groups that are created here and what happens when someone tells you to connect with them through Skype. I have just recently started adding people to my Skype and I wanted to know what the expectations are. Do you do video calls or voice calls or you just use IM? Also, some people tell you to add them to Skype and after adding them they just go all quite, they don't respond to messages. What does that mean? Has that happened to you?
