I think previous message board posts made by other users in all Yahoo Fantasy Sports Leagues should be viewable by all members. I noticed that from the seasons 2011 to 2017 I can not view the messages posted by other users. I do not know why this feature was changed but I think for league history purposes it should be made viewable once again, especially for commissioners. If Yahoo Fantasy Sports wants leagues to last for years members should be able to go back and see what other member wrote on the message board, particularly when Yahoo allows us to see all past draft results, final team rosters, and even every transaction that ever took place. Please vote for this feature to be reestablished. Thank you for your time.
Yeah I've noticed some weirdness with this, too. It seems like some years in your given range (2011 to 2017) are fine, but others are not. I agree that older than 2011 seems to be perfectly fine. Chalk it up to another Yahoo quirk, but I hope the messages are not lost forever!
