Is that true? That would be wonderful.
In fact, I cannot remember any email from the Scratch web site for email verification or something.
On the other hand I think it is very important that students have an account so they can upload their projects connect with others and receive feedback. That is now a must if they are using v.2.0 but when using v.1.4 students that didn't create an account just lost half or more of the Scratch experience. Sharing an account is also a bad idea.
