పూర్వం, మనుషులు దారి పక్కన రాళ్ళు పోగుచేసేవారు.
తర్వాత అదే దారిలో నడిచేవారి కోసం.
దీనినే, Cairn అంటాం.

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.
