I need authors to inform their CPF (brazilian personal identification number) at paper registration, so we can certificate their presentation after the conference. I changed a field I didn’t need at the user registration/profile form to have “CPF” as its label. However, I noticed co-authors don’t need to be registered as users, so this solution didn’t work for the last conference.
With this, I ask your help about the best way to proceed. How to add a custom data field to authors in OCS? I may need to add other custom fields (e.g. identification of the advisor, which is mandatory in a specific conference).
I read about how to add custom field in this post Add new field to registration form, but it applies to users only.
