Make attachments required per forum

[ugr|dual]

We are heavily using the attachment uploads. Got an extra export tool to mass host them on other servers and convert them to inline-img and all that..

.. but what I really need is a way to make attachments mandatory for new threads in certain classified ads forums. So users who din't upload any can not submit the new thread.

Any idea how I could make that work?

If you wrote a hack that does that or would write one, maybe you would find our attachment exporter useful.
