The only option available for users who play on a website that is not listed is to manually import their league into My Playbook. When going through the league import process, on the page that allow you to choose the website where your league is hosted, please click on the "Other" option. Next, click on the league host drop-down box and choose "Other (Plain Text)."
Now you'll see a large text box on the screen. You must enter all your league rosters into that text box by putting the team name on the first line, followed by players names/teams each on one line. Please be sure to skip a line between each team.
Please be sure to follow the suggested player text format and click on the "view Example" link so that you can see how to properly format the data you're inputting into the text box. Once you're done inputting the rosters. Then click on the blue "Import" button.
