When groups first popped up with the release of BlackBerry Messenger 5.0, there was no documention about them at all, and everyone pretty much had to figure it out on their own. Over time, those that chose to use groups got a pretty good handle on everything. I for one love the functionality of the BlackBerry Messenger Groups (although I didn't at first) and use them every day. The ability to easily share photos, calendars and lists makes some of my daily tasks as well as communicating with family and friends much easier. Take a look at thie video above to get a better idea of what groups can do, and see if you've been missing out on any of the cool integration.
