The reason was that I saw this meme, and then remembered sending over ten QSL cards to the Japanese JARL Buro a few days ago, confirming my FT8 contacts while on vacation in Fuzhou during the winter break. (Then I got chills.)

I'm wondering if anyone has used CRAC Buro and can report on its efficiency, as well as the typical QSL card delivery cycle.
And, if CRAC Buro really needs more people, could they recruit more volunteers to help with distribution? Currently, it seems like there's only one person in charge per province.
