I’ve changed my eamil and now all my progress and my donation are gone, how do I get all that back or do I have to start over?
Your account is linked to your email. So, if you plan to use a new email address, and want to keep the same freeCodeCamp account, you need to go to your settings and change your email address.
So, I suggest logging into freeCodeCamp with your old email address, then doing the above.
Hope this helps
