How to take good pictures at a party?

I have a Nikon D60. Its like a club and its going to be really dark. What should I set my camera to and that kind of stuff.

You'll have to use flash because time exposure will give you nothing but blur.

What kind of lens do you have? What is the smallest number on it with F next to it? Like f2.8 or f4 or 5.6. The best thing to do is to choose A on your camera and turn the dial so you'll get the smallest number like f2. The smaller the number, the larger the aperture, the faster the shutter speed, the less blurry the photo. If your shutter speed is faster than 1/60 then you will be fine (like 1/125 or 1/250 but since it will be dark, i highly doubt that) and set your ISO on 800, if you still get very blurry photos, set the ISO on 1600 or even 3200 but the higher you go, the more noise on your photos.you'll have a great advantage if your lens has Image Stabilizer which is usually written on the lens itself or you see IS on it.

so to make it short:

choose A
choose the smallest number by turning the dial on your camera (next to your right thumb)
set ISO on 800, if your photos are very blurry set it on 1600, if still blurry set it on 3200 (it might say High ISO for 3200)
if it says Image Stabilizer on your camera, then there will be a button on it, set it on ON.
(EDIT: if you are using a Nikon lens, there will be VR (Vibration Reduction) instead of IS, they are the same thing.

have fun.

EDIT: you can also use flash but flash usually makes the background of your photo darker.
EDIT 2: choose Night Portrait on your camera (it's on the dial, next to M)
