The internet's popularity to a large extent is about the sharing of information. Some of that information is practical, some of it important-and some of it is just fun or interesting. We started collecting images sent to us via email on topics of general interest, the kind of images and information that when you see it you say, ''Now that's cool,'' or ''Wow,'' or ''Can you believe that?'' We encourage you to visit eTree to see the latest images and to email us ones you'd like to share.
