I want to change my username. As I know there is no such functionality in codechef(admins comment confirming that), so I have to create a new account and delete my current one. But what will happen to my laddus? Will I be able to connect my current laddus to my new profile? Will I be able to use my laddus in the future? Currently I have 150 laddus and don’t want to lose them. Can you, please, tell how to save them?
