You can add your project as long as they are made in Scratch other wise you have to re-start the game because it will stop all. When you are done browsing then press space to go back to the main menu. When you browse games and find one that you want to go to then highlight that link and then copy (control-c if you are in a windows or chromebook, command-c if you are on a macbook.) after that paste in into the U.R.L. bar above (control-v if you are on a windows or chromebook, command-v if you are on a macbook).
