Comment 3 for bug 296237

I understand that argument.

Perhaps it should be strongly urged, but I cannot think of a way to emphasize the importance of including the source to the casual submitter.

I would like to see as many materials as possible. However, since many of the materials that will be submitted are highly specialized, the material will be almost useless.

Example: http://ubuntu.ec/su/drupal5/files/poster2.jpg
It is in a specific language. Since there is no source, it cannot be translated.
It is designed for a specific release party, so there is no way for other release parties to use this material.
