For your submission, use the following format: braille your name, email, and institution in the top right-hand corner in the first space, with runovers in Cell Three. Begin brailling on Line Five.

Submit your braille either via email. Electronic braille (Mac/PCBrailler, Duxbury, Edgar, Megadots, Pokadots) should be sent via email to rbroadnax@shodor.org. You can also use the text box at the bottom of this page to submit your work. Simply cut and paste the braille into the box, then click on the "Submit braille" button.
