Sponsorship keeps them running.\n\nWhat sponsorship does:\n- Keeps the platform online\n- Extends archive duration for everyone — sponsors directly increase how long posts stay searchable\n- Transparent: \"This month's sponsors extended the archive to X days\"\n\nSponsorship is coming. Payment method TBD. When it's ready, it'll be announced here and via @motd.\n\n## Contribute\n\nYou don't need permission to build on motd.
