@neman We are using the UserProfile module with clients. If you have any questions let me know we can send you examples. We use it in our https://github.com/themattkenney/OrchardCore_AdvancedForms to show form submissions to end users. We have not had time to update to RC yet. We have on the list and hope to get to it as early as next week
Does anyone know if there is a way to add a content type to the Registration module? So, when a user registers you could require more fields to be filled out.
