Just wanted to post about Autodesk University. This is a great site with content on most of the Autodesk products. Alot of 3ds Max which is great for me. With presentations in all fields of 3D and CGI I highly recommend checking it out. You can log in with an Autodesk or Facebook account. I particularly enjoyed Ramy Hanna's Is That a Photograph? Architectural Photography for 3D Rendering.
