how do I know which email belongs to my old username

[Germio Rambharos]

It seems that I have multiple accounts (usernames). But I dont know which email is used for those usernames. I want to remove them

Welcome to the community @Germio Rambharos !

I don't believe that community can help out much, best case here is to open a support ticket for Trello. You will be asked some questions about those accounts.
