When you sign in you are in the affiliate dashboard, which is your daily records. If you scroll down to active players, you see a green link “view active player report”.
When you click on that you see your active players. To view more than fifty, click on the dropdown “rows” and pick how many you want to see.
You can then click on the player’s user ID and find out even more.
I love all the player info you can get, it really helps to know who does wel fr you, so you can target those groups.
