What if I previously set up my ESPN or Yahoo league on Fleaflicker, can I get the league history added?

We don't currently have a way to merge the two together, but here are two things you could consider doing:

1. Import the league from ESPN and if you like what you see and it has more of what you need long-term, update it to mimic the existing Fleaflicker league and then transition everyone to the imported league (just send them new invites). You could then opt to delete the other league when you are ready.
2. The other option is to import a second copy of your league to keep on our site for future reference.
