How invitations work

Last updated July 10, 2026

1. A Client reserves your Edition

Your Legacy Mark Client purchases a Mark link and assigns it to your email address. The email contains a random, expiring, single-use link.

2. Sign in with the invited email

Create or open your Cosmic Portals account using the exact recipient address. Verify that address, then accept the invitation. The purchased Edition is applied by the server and cannot be changed from the browser.

3. Build and submit

The Mark joins your dashboard. Complete Details, Media, Story, Review, and Terms. When the system confirms all Edition requirements are present, submit it to the private review queue.

Need a new invitation?

An expired or revoked invitation releases the unused link back to the Client. Ask that Client to send a new link. Return to My Marks.
