Can People Who Are Not Invitees (aka "Tribute Participants") Submit Videos?

you can share your Tribute with as many people as you want with the custom URL

You don’t have to be a Tribute invitee to submit a video for a Tribute. Anyone can submit a video message by following the custom URL you created for the Tribute. (ex: www.tribute/xxx)

If you set a password to the Tribute page, you should include it when sharing the URL with others since only invitees receive email reminders providing the password.

You can share the URL with as many people as you’d like so they can also be part of this meaningful gift!
