There is an app I thought you folks might wish to know about. It is called Zello Walky Talky. If you type in Zello, you should find the app. It is available for Android, BlackBerry, and IPhone. It is also available for the PC. It is a social networking app that allows real-time voice chat. It is much like the CB radio. Once can add contacts and speak to them in two-way mode. Once can also join and create channels, which are like user groups. There are several Scottish and Irish channels as well as a Celtic Music hannel, which I have created. Hope to see you there. Oh, it's free.
