Can I share a class with another teacher, can i add them to my course as a teacher?
@MrCosentino the way it is set up right now, courses can only have one owner/admin. So the short answer is no.
One workaround is to share your account credentials with this other teacher (obviously, only do this if you are comfortable - this teacher would be able to access your entire account).
There is nothing preventing two clients/browsers from being simultaneously logged in as the course owner and doing things like creating exercises and grading, etc. The classroom UI doesn’t auto-refresh in real time (e.g., Google Docs), so you would want to make sure to refresh the page if you needed to see anything created by this other teacher in real time.
Hope this helps!
