The card office is good, it has greatly benefited many hams. Not everyone has the time and energy to collect QSL cards through direct methods. I suggest that both CRAC Buro and local card offices should recruit volunteers from their province through online channels, either because there are more people working together or because they can learn from JARL Buro's system and efficiency. It seems that CRAC Buro is often criticized, and it deserves some criticism.
