פעם, היו אנשים מניחים אבנים לאורך הדרך.
למי שיעבור אחר־כך באותה הדרך.
לזה, קוראים Cairn.

Cairn keeps three messages of up to 50 letters each in a public archive. The first is placed at purchase; the other two any time within 50 years.

One payment: $15 / $9 / $3 for the three stones, depending on your region. No subscription, no further fees.

Every stone is public. Signed with your name, a pen name, or no name at all.

Cairn has just begun. In this first season an invitation is free — write to support@c4irn.net.
