Deleting a Classroom
I created a classroom to see what it was like, how do I delete it?
You're confusing two different things. As Vivisaurus says, your account and your classroom are two different things.
If you want to delete your classroom, then use the instructions I've posted above.
If you want to change your email address, click on your username at the top of the screen, and choose settings.
If you want to learn a language using Duolingo, don't create a new account, just click on duolingo at the top left of the page, and start using the course.
I am not able to change my email. I have tried several times but it never saves, and I've tried reloading the page but it never works.
Last time I tried to use French as my root language, it deleted my languages and switched everything to French.
Thank you all for your help, I will try again.
There's an ongoing problem with the interface. When you switch your home language, you only see the courses you're using from that home language. When you switch your home language back again, all your courses will be right where you left them.
I don't know what's going on with your email, though - does it give you an error message?
