Contact all presenters to upload the material

Dear Indico folks,

After the conference, a lot of presenters have not yet uploaded their presentation. Is there a way in Indico 3.1 to filter all these, and contact them using Indico?

Kind regards,

Paul

A “has files” filter sound useful indeed (github issue please ;)).

What you can already do right now is simply sort the contribution list by the “Material” column and then select the ones without any files.
