There is no official transfer from ESPN, Yahoo, or NFL.com. One person — usually the commissioner — uploads screenshots of the whole room, or pastes a Sleeper league id. We rebuild it by hand as a private Live Fantasy league.
1One person sends the whole room — usually the commissioner. This is not an invite, and other managers do not upload their own teams here.
2Upload screenshots from your photo library: settings, scoring, standings, and one roster shot per team. A Sleeper league id can stand in for photos.
3Add each manager’s email, @username, or FML user id if you have it. We keep that on file and send invites when the room is ready. Rebuild is still by hand, so teams will not appear instantly.
This is not a live sync. Week 1 on FML still starts from our calendar.
