Re: Etoys Again: saving a project

I am glad to see etoysillinois.org is still alive. And I am mildly
surprised that a .pr file can be loaded into a 6.1 based Etoys. I guess
somebody worked on it so that  an SExp based project can be loaded into it.
(thanks)

I can load and "save" a project from etoysillinois.org onto
https://squeak.js.org/etoys/ which is definitely compatible. The "save" has
quotes as it does not let you simply download.
