there are seveal ways to run a keeper league in any sport, here is how i do it, so that all owners have access to the information all season / off season.

start a league, invite your friends / people you know will stay active. draft the league & play the season out.

after the season starts, start a free group on yahoo & invite all the members of your league. they will need to be there.
http://groups.yahoo.com/start

at the end of the season copy each team’s final roster & paste them in the FILES section. make a seperate file for each year, final results & draft order for the next season.

use the MESSAGE BOARD to keep in contact in the off season, post your keepers (you will need to make a file for keepers as well), make off season trades & you can even draft the 2nd season on the message board.

use the POLLS section to vote on rule changes or off season trades.

future DRAFTS, you can draft on the message board in your group, do a LIVE draft but the 1st 6 (or however many keepers you have) rounds must be your keepers. i’ve done it both ways but recently we are drafting in the league. i put all the keepers on each team, set the season to ready & set waivers to 0 days. when it’s your pick, grab the guy you want off the waiver wire & then the next guy will follow. we are using a 24 hour clock, you have 24 hours to make a pick, then you e-mail or call the next guy.
