My house rule:After a blank tile has been played, a player can replace it with the real letter that it represents at the start of their turn. They get no points for the letter they just lost, but they do get a blank to use. Then they must use the blank in the word they make that same turn. No hoarding blanks.
Can't afford to pay for food, but CAN afford to drop several hundred dollars on a smart phone, plus the $35 or so every month to keep it online? What a great country we live in!
