You can go to Learn -> Game Explorer and change the drop-down from Master Games to My Chess Games. Then chose whether you are interested in your moves as White or Black. You will be able to see what you have played in your previous online/correspondence games (I'm pretty sure Live is not included in that).
Is that what you are looking for?
I'm new to this website since last November, does anyone know a way if I wanted to access my own opening repertoire on chess.com how I could possibly set this up? Thank you to everyone that can assist!
