I finally did my first game after becoming "official."  Actually, it turned out to be FOUR junior high girls games.  (Legs were a little tired.)  
All went pretty well.  I missed a few calls that I was aware of...and I'm sure some more that I wasn't aware of 
 
But, I got some nice compliments from my partners (two games with one guy and the next two with another guy) and from  the guy who runs the league.
Thanks to all on this forum.  I was a bit nervous, but I've learned a great deal reading discussions here and that gave me some degree of confidence.
