NO LIMIT TO JOKER EXCHANGES (Article 78)

Commentary: After a player has started their turn by picking a tile from the wall or making an exposure after claiming a discard, they can exchange as many jokers as they want from any player’s rack including their own.

Question from a player:  I had two jokers which I could redeem during my turn.  Another player told me I could only redeem one joker per turn.  Is this a rule?  
 
Answer from the NMJL:  “A player may make as many Joker exchanges on a single turn as their tiles dictate.”
