John and Andrew:
We're glad to hear that you guys are such passionate Fantasy Football commishs that you want to set up keeper leagues here with Yahoo!
First-year keeper leagues don't use the Keeper Management tools that are available to commissioners of existing leagues that are renewing this summer.
If your owners draft, and then want to declare keepers after the season, you can keep track of that information offline during the offseason, then enter those keepers into the system next year using our Keeper tools.
However, if your owners already have keeper players in mind that you want to enter into the system before you draft, you can use the Edit Draft Order & Assign Keeper Players tool to do that.
Using the Edit Draft Order & Assign Keeper Players tool
I hope this helps you guys in setting up your leagues this season.
If you have any other questions, please feel free to reply to this thread. Thanks again!
