A group card that goes round

Sign it and pass the link on. The last one seals it, and they break the wax seal to read every message.

Questions

How does a group card work?
Start it, write your message and press Pass it on. Send the new link to the next person. Each person adds a line and passes on their own new link. Whoever signs last presses Seal it and sends the sealed link to the person it is for.
Is it free? Do people need an account?
Yes, it is free, and nobody needs an account or an email address. Everyone just opens a link.
Can I change the design?
Four themes are free. Every premade envelope, eight paper colours and ten seal stamps come with paid plans: log in, then start the card.
How many people can sign?
Up to 25 messages of 140 characters each.
Where are the messages kept?
Inside the link itself. Nothing is saved on our side, so keep the last link: it is the card.
