My guess is that you are behind a firewall that restricts access to certain sites. Businesses like to restrict access to bandwidth-hungry sites such as photo and video sites. Are you on a computer at work?
B&H rocks! I don't have any outstanding orders with them yet I got a package from them yesterday and this morning UPS notified me that they are going to deliver another package today. Yipee, suprise gifts!
I liked the lynda.com Ben Long series on digital photography fundementals - good for beginners. I also learned what I know about Photoshop from watching lynda.com videos. Is it worth it - you have to be the judge of that, but I think it is because of the diverse menu of courses, the quality of the videos, and the (optional) ability to download course files to follow along with the videos. I don't mind paying for a quality product.
