Can someone tell me what are the advantages of using Raw vs JPG. I hear more people useing Raw and not sure why, I use Lightroom 2 and can adjust a jpg just as good as a raw file. What am I missing.

There is a difference between Raw and Jpeg. Jpegs are compressed image files. Some of the data in the file is thrown away by the camera when saving to the memory card. With Raw, everything is saved.

I read recently somewhere that if you take a Jpeg image, alter it and then re-save again you throw a part of the data (and therefore quality) away again. This is why the general concensus is that you shoot in raw, process your image then save to Jpeg when you are finished, or alternatively you save it to Tiff format which is another “lossless” image compression protocol. I’m not 100% “up” on the differences myself yet but have started to shoot exclusively in Raw and then convert to Tiff for storage, and leave Jpegs alone. I don’t really do much in the way of post processing yet beyond that as although I have CS3 I still have no idea how to use it! I recently bought a nice big book on the subject…
