The guys from Rigging Mentor have announced a name change to "Rigging Dojo" and the website has been updated with the new name as well ->

"We are still the same group of guys that are solely focused on training and educating students, professionals, and companies, in the art and science of character rigging and setup. We feel that to help set us apart from the rest of the CG training and mentoring sites that you can find out there, we needed a name that is unique to the field, as well as a name that describes the type of education that you can receive from us. We are a mentor-based education online school, which means you will always get a professional that is working in the field to train you in the technical arts. Our training adjusts to your skill level to give you the best possible education you can get, whether that means you’re trying to get your first job, or you’re simply wanting to update your current skills."

I know all three of the guys that founded and run Rigging Dojo. They are top notch and are all highly regarded in the industry.  If you're looking to learn the tricks of the trade or just beef up on your existing skills these guys can help you.  You can learn a little bit about them here ->
