At the moment ZOO 2.0 does not have front-end submission. The developers state this very clearly over and over again. This issue has been beaten to death in the forums and elsewhere. If you need this capability then ZOO is not for you, at least at the moment. I think ZOO started out as basically a catalog component and the developers did not feel front-end submission was real important. I am sure they have gotten the message and are working on it for a up coming release. Other than that limitation, which is a big one for a lot of people, this is a great component!!! Very excited to see what I can create with it and what others are going to do.
