Brian Kusko walks you through adding your Not For Sale animals into MorphMarket, using import 2.0 (part 1). Brian is able to do this even while being sick, so you can too. ;)
Note that you don't need to use import to accomplish this. If you want to keep it simple, just use the "Add Animal" option to add them one by one. But if you have more than 10-20 animals it's recommended to learn this approach.
