Write a letter now. Opens in a day, a year, or 100 years
Write a letter, add photos, voice or video, and pick the day it opens: tomorrow or 2126. Send it to yourself, someone you love, or a group. The server keeps it sealed until then, and recipients always open it free.
A source that found nothing is a measurement. A source that has not run is a gap. Neither means the launch lacks the thing.
