- social.biggame.fantasy.leagueSpace space One league's play, readable by its members. The authority is the account the league's charter was written to, and the members are the league's own.
- social.biggame.fantasy.permissions permission-set
- social.biggame.fantasy.queue space One member's draft boards. The authority is the member and the space admits nobody else, so a board is private in the only way a space can make anything private.
- social.biggame.fantasy.trade space One trade negotiation. The authority is the proposing owner and the only member is the team being asked, so the space is the two of them and nobody else.
