Great resources on the web for photogs

A couple of months ago I purchased Lightroom 2 and installed it and was confused on how to use it. But was saved by Apple itunes of all things! I did a search in the pod casts section usually at the bottom of the storefront and found a great bunch of video podcasts titled "Lightroom for Digital Photographers" hosted by Michael Rather from the digital photography connection. These are fantastic little short tutoring sessions by some one who knows their stuff! Check it out even if you are pretty experienced with Lightroom I think you will learn something new. I literly learned the entire program while I did other work in my studio!
