Congratulations! The D3100 was my first DSLR. You will become very fond of that camera body. It has a qreat sensor and a lot of "Bang for the Buck". You will be pleased with the detail that camera offers. Take LOTS of pictures... of everything. You will get used to the controls and what works (and doesn't) for you. Lots of helpful tips on YouTube from many sources. ...a lot for beginners. Most of all - HAVE FUN. That is a fantastic camera to carry around all the time. It's light and compact and once you're familiar with exposure, you will like the control the manual mode gives you over the pictures you take. The more you shoot, the easier it will become. Be sure to post some of your pix on this site, and take a look at the other's galleries. It will give you lots of ideas on what to shoot and how to frame a shot. I'm very excited for you, because I know how much fun that camera was for me. Good luck and looking forward to seeing your pictures.
