 * For the Datasheet, you have the option of either uploading a PDF that you have on your computer, or just pasting a link you found on the internet. If you upload a file, it will be stored on our servers, so that means we will have it even after it gets completely removed from the internet. Pasting a link is quicker, though, so I get it if you do that instead.
