I am a retired teacher from Northern Illinois University. I attended the codap session at NSTA 2016 on Saturday, April 2. I am interested in doing some development with codap, but acquiring an account means I have to specify a school district. Obviously, I am not with any specific school district, being retired. Is there some way that I can still get a codap account. It seems that when logging in as a guest, I cannot save my work in any way. It gets lost when I leave the codap environment.
Thanks for any assistance you can provide.
