In the QSL card exchange system at your station, although the various application processes are very complete, it is difficult to record information such as [the time of submitting the exchange request] and [the time when the other party agrees], which often requires manually reviewing and flipping through cards to verify whether they have been shipped. Sometimes, forgetting whether a card from another station has been sent results in repeated shipments. Although there is an email notification system, ultimately the operation still takes place within the station. Currently, most people record this information by posting personal messages in the station's exchange area, but could you add a checkbox option for "[Personal Page] - [QSL Record]" in the table to indicate whether the card has been shipped?
