Which, now that I think about it, I can't post the paper work I have for the X and R blocks on the web. Some day I'll learn how and we can post that stuff and make it a sticky.

You need your documents scanned so you either have them as ***.jpg (image) or ***.pdf, then you press 'More Options' at the bottom right of the reply box, 'Upload Photos' where you choose your scanned documents, upload them and bingo. Hopefully.
