Please be respectful of our system - if you are on the shared servers then be mindful of putting huge numbers of links in a sheet to be archived. Please email us at: firstname.lastname@example.org if you need many thousand processed before you try. Many hundred are usually okay, but if you try and download a YouTube video hours in length it will tie the system up for a long time processing that. Email if unsure.
