Hi Ree.
Welcome to our little community. Rebecca and I use a D3100 when we don't want to carry around our larger cameras, so we can definitely help you get the most from that wonderful little camera.
So what makes a photographer better? Practice, practice, practice!
Please don't hesitate to ask any questions. It's a good bet that somebody out there has the same question, but is just too shy to ask.
We'll look forward to seeing some of your images.
Keith
