I have the same issue with Alextheplayer23. I forgot my password and my email I used for it but I remember the username. Unfortunately I don't have screenshots of me playing in the account. It was AnnikaNika and I would mostly play with Martin the bot in that account. Please help me recover it!
EDIT: Before I commented this I already sent an email to support@chess.com so please check your inbox for mine! <3
I lost my password but I don't have an account
