Summary

  • Postcrossing introduced an inactive state in February 2008; later instructions tied it to pausing new address assignments and preserving postcards due on return.
  • By June 2018, Travel Mode also separated a member's home address from the place they were sending cards from.

A website can stay awake all summer. The person with the letterbox has other plans. For Postcrossing, a service built around people sending real postcards, that difference eventually deserved its own setting.

The project opened on 14 July 2005. Its fifth-anniversary account credited volunteers and members with keeping it going. Behind the cheerful exchange sat an awkward dependency: somebody had to be available at the address handed to the next sender. A perfectly functioning website could arrange a perfectly inconvenient delivery.

In the redesign announced on 15 February 2008, an inactive state appeared among the new features. Its advertised occasion was wonderfully ordinary: going on holiday. The Internet had acquired another way to respect a suitcase.

A July 2012 reminder explained the bargain. Set the account to inactive and Postcrossing would stop giving the member's address to other participants. Return to active and the postcards due to that member would follow. The system remembered the return a participant was owed while suspending new invitations to write to an empty home.

That control sat at the address-allocation stage. A postcard already posted remained in the postal system, which explains the practical importance of advance notice. By June 2017, the official advice was to switch a few weeks before leaving. The same notice explicitly allowed members to keep sending. A holiday could close the receiving side while leaving the pen in business.

Then came a second geographical problem: the writer might have moved temporarily while the account still pointed home. In a June 2018 holiday notice, Postcrossing described Travel Mode. Members set a destination, connected through a local Internet connection after arriving, and sent local cards with the corresponding postcard identifiers, maps and statistics. Both travel and inactive settings stopped further distribution of the home address; due cards remained recorded until the account became active again.

This was a surprisingly careful vocabulary for a simple hobby. Home address, current sending location and readiness to receive had become three separate facts. Members could be enthusiastic, online and hundreds of miles from their letterbox at the same time. Postcrossing's job included letting the letterbox take the hint.
