How to add file upload member field in Users and groups

Hi I want to add a file upload field as members field in Users and Groups

...supposed to do what exactly?

-aj

In Site Setup --> User & Groups there is a tab called Member Fields, which provides options to create new Member fields I want to create a new field for FileUpload so that when I create or update a User I have a field where I can upload a PDF or VCF file.

But when I try to create a new field the Field type drop-down does not have a file upload field option.

How to add the MemberFiledsFileUpload option in that drop-down while defining a new fields

You could use a Rich Text and include a link to the PDF

Now whenever I try to add a new filed it shows me this message

Error
There were some errors.

It does not even show me the error trace, any idea what can be the reason, if I try to edit the existing field using settings link, when I try to save the fields it shows following error

Traceback (innermost last):

You could try this approach (and add the Blob field in xml).
