[BlindMath] Typing Math and Science Quickly and Understandably

Thu May 3 20:09:19 UTC 2018

Hi Louis and Rosanne,

Thanks for sharing the contact details of Dr. Cary Supalo as well as
about his organisation. I have briefly went through his website, and
will surely reach out to him in the future if the need arises. I will
also shortly be reading the summary of the STEM seminar of the 2017
NFB Convvention which you shared, Louis. Many thanks once again for
sharing all these resources.

Thanks.
