It should happen automatically. There is nothing that you need to do. I just looked you have 129 games as white and a similar number as black. Are some missing?
"My games" in explore
If you need help, please contact our Help and Support team.
In the explore-function in OLC i can select "my games" instead of "master games". I'd like to use this option for my openings-experiences. But how can i insert my current or finished game into "my"database. If it can't be done easely, the my-games-option doesn't seem of use to me. I could not find a faq about this
