If any of you are into the challenges aspect of Geocaching, there is a new smart phone app just for the challenges.  Look for it in your Droid or Apple app stores under Geocaching challenges.  Very user friendly and easy to use.  FYI for anyone interested.....

Yes it is run by Groundspeak and GC.com.  I see there was another thread in some forum area already on the Droid app.  Don't mean to be repetitive, just shouting out to the masses.  We have done a bunch of them, and just like Geocaching, we pick and choose what we want do complete.  Challenges to us, are just another one of the many facets of Geocaching....
