Messages in Mountain Lion

        John Carter passes on this info from TakeControl publishers:  "Communicate more effectively with 'Take Control of Messages in Mountain Lion.'
        "In 10.8 Mountain Lion, Apple replaced the long-standing iChat program with Messages, which takes its interface cues from the iPad version of the program. Although Messages looks easy, many people have had trouble understanding how to integrate different chat services and Apple devices, now that messages can appear on Macs, iPhones, and iPads. 
        "For instance, should you use iMessage or AIM to chat with your friend? What if he's home on his Mac or out while using his iPhone? Can you add someone else to the chat? What if you want to switch to an audio chat? To video? For video, should you use Google Talk or FaceTime? And so on. The mechanics may be simple, but the setup and human interactions are anything but.
        "To bring some sense to the situation, we asked networking guru Glenn Fleishman to explain how you can bend Messages to your will, and the fruits of his labor are now available in the 113-page 'Take Control of Messages in Mountain Lion.' The book normally costs $10, but the 30% MUG discount drops that to $7. Learn more about the book via the coupon-loaded link —
