Someone is leaving.
Give them a card the whole team actually signs.
One link.
You make the card and share one link. Nobody who signs needs an account, a password or an app.
A pen, photos, GIFs, and your own Slack emoji.
People can sign it by hand, the way a card gets signed. A few words fill a sheet. A long goodbye reads like a letter. Photos are never cropped.
It sends itself.
Pick their last day and a time. The card is emailed to them once, at that minute, and you can see that it went.
Then it is theirs.
The card keeps its own address and saves as a PDF, so it is still there long after the leaving drinks.
