Looks nice,
I wanted to submit a project and I spent time to fill the forms but I was greeted with a login wall after I filled all the details. There was no indication anywhere in the process that it would be required. It made me feel somewhat deceived.
I think it would be more honest towards your users to be upfront that you require login to submit a project.
