This is a question about deleting previously registered account information.

[임동규]

Hi!

I'm trying to register 'hyjun@celimax.co.kr' on Trello, but since it's an account that has been previously registered, existing information is viewed like the picture when registering.The person who used the account before and the person who registered and used it now are different.
Therefore, I hope that you do not automatically click the icon like the picture, but register it as a new one.
If possible, please reset your existing account information.
I ask for an answer. thank you.

There is no way to do this, the email address is effectively the unique identifier for an account, and it belongs to the person who originally used it.

It's a very very bad practice to reuse emails for different people, and actually illegal in many countries - your new user should have a different email address.
