How do I use "Message" on my iPad 2 (wi-fi only)? Better question...What is Message (I think it may also be called iMessage)? I've been reading places on the forum where people talk about having problems with Message and FaceTime (I don't know what that is either, but one thing at a time). I've done searches for "Message" on the forum, but come up empty. Any help would be appreciated. Do I need to know others that have an iPad?
