Bring the room with you
There is no official transfer from ESPN, Yahoo, or NFL.com. What works today: you photograph the league — standings, settings, scoring, and each roster — and we rebuild it on FML as a private Live Fantasy room. If it is on Sleeper, paste the league id and we can read the public roster list for you.
This is not a live sync. After we rebuild it, you get an invite code for your managers. Week 1 on FML still starts from our calendar.
