How can i set a required Field at registration for the Image or PDF upload? I'm working at a businessweb and i need to verify the identity of users. I want to get the copy of trade licence from my users. Please help me! Thanks a lot!!!

You need to write a custom plugin for that. See downloads (RC2 - documentation) for instructions how plugins are coded.

I need something similar in the long run, so if you start programming this, please keep me updated.

Write a custom plugin for that? Oh.......it seems really hard....

I've already submited that option on the forge as a feature request. We will have to wait and see
