Just a head's up.
I run another league on yahoo, which was supposed to draft last night. About 20 minutes before the draft, I received an e-mail from yahoo that they were having system issues, and therefore, they were changing my league from live draft to autodraft. I did manage to reschedule the live draft, but if it happens again tonight, we are too close to the start of the season to change the draft time, so it could become an autodraft.
There has been no indication that the problem continues, and this is the first time this has happened in 15 years of having leagues on yahoo. Hopefully all goes well.
Just in case, I would recommend that everyone go to the site and ensure the player rankings are to your liking.
