I just signed up and paid for the machine knitting 1 and don't know how to find it. Please assist me in finding out where to go for the online class.

My understanding is that it is not an online class but a correspondence course (same as the handknitting courses). According to the description on the TKGA Web site you will be receiving study materials in the mail. Once you master the initial how-tos, you will complete a group of swatches which you will submit for critique.
