Repl.it Classroom is the best. Unfortunately some policy wonks in my district are wanting to deny us the option of using Repl.it because you aren't part of the California Student Privacy Alliance, you aren't a signatory on the Student Privacy Pledge, and you don't state on your legal page that your are COPPA compliant. They seem to care more about checking these boxes than actually looking at the really nice and secure environment you've created. Maybe when you aren't too busy creating great software, you can check some of those butt coverage boxes that some administrators care about. Thanks.
