tbf cards makes online group cards for a birthday, a leaving do, a thank-you, a retirement, a wedding, a new baby and twenty other occasions. You pick a card, share one link, and everyone who gets the link writes their own message. They can add photos and short videos too. The person it is for opens the card on the day and reads the messages one at a time.

Nobody needs an account to sign. The link opens in a browser on a phone or a laptop, the writer types their message, puts their name on it, and that is all. The organiser sees the card fill up and can take a message off if it should not be there.

A card from one person works the same way, with one message instead of many, for somebody you want to write to on their own.

Pricing: a group card is £4.99 and a card from one person is £2.99, paid once by the person who starts it. Writers pay nothing.

There is a finished sample card to read at tbfcards.com/card/sample/ before you start one, and a list of every occasion at tbfcards.com/card/. Every occasion has its own card design, and the person who starts it chooses the day the card opens, so nothing is seen early.
