Team Managers in League Manager leagues are able to use a league-specific chat channel to communicate with the league or another manager. There will also be a Matchup Chat channel where you can banter and smack talk with your opponent.
The chat feature works on PC, mobile web, and the ESPN Fantasy App (iOS and Android versions).
Where did Smack Boards go?
Each matchup period will automatically create a direct chat with your matchup opponent similar to Smack Boards. This conversation will be listed just below your League Chat in the list of conversations.
Are my old League Chats and Message Board posts gone?
Message boards will continue to exist on desktop, but League Chats prior to the new Fantasy Chat will not be available in the new Chat experience.
