I have a student project that needs my group members to work together with me.
But we cant seem to have it going.
How to collaborate on the same Scratch Project with my friends like a google document?

I don't think that this is possible right now and I think that the suggestion to add this is rejected (the scratch team doesn't want to add it). The only way I know of right now is to use remixing.

Alright thanks so much!
