Okay. So, you can, also, utilize Skype for conference calls and presentations. So, you double click along the friends on your friends list and then you click the "add person" tab. Choose whoever you'd like, click "add," and then you should see both people in a conversation together. Then you hit the green call button, and boom. You're in a conference with two people. You can make a video for free, but in order to make a conference call you have to add a Skype credit. So, that's how you make a conference call while using Skype.
