Camfrog Video Chat is a modern chat client that allows real time video, audio and text chats with up to thousands of participants. The tool enables seeing, speaking and writing to other chat room members simultaneously. Not all video chats require you to have a Webcam, so you can also participate without a camera. Camfrog chats are either private or public and you can make calls to mobile or landline phones. A range of parental controls in Camfrog Video Chat help to protect minors from revealing too much of their privacy and from joining certain chat rooms when using the Instant Messenger. Other settings of the Skype competitor include Privacy and Safety, Video and Audio, History, Languages, and Hotkeys.
 Windows Live Messenger makes it easier than ever to stay connected to the people you care about.

• Favorites and groups - Put the people you chat with most at the top of your contacts, so you easily see when they're online. Want to chat with several people in one window? Just set up a group.
• Share photos - Look at photos together, right in the conversation window. And Messenger tells you when people you know post new photos on Windows Live.
• Customize - Show off your personal style with custom scenes, animated display pictures, and signature sounds.
• Mobile and web - Using a public computer without Messenger? No problem! You can chat on the web from Windows Live Hotmail. Or, use Messenger on your mobile phone
