MyBB Community Forums

Hi,
I'm using MyBB in our college and we want to ask students to upload their ID cards while they're registering in forum so the admin can decide to confirm their registration or not. please help me how can I implement such function in MyBB?
It's obvious that the uploaded photos should be emailed to admin or stored on a place that users can not see it because it's their private card. 
Thank you

You can use a profile field visible only for admins, but it doesn't allow file uploads. For that you'll need a plugin.

What plugin is required? is it possible to redirect them to another page with a form when they hit the submit button at bottom of registration form?
