Hosts can remove signatures from the back of all cards.
Click on the small gear icon next to your name and select the "Settings" button:
On the next screen, uncheck the box next to "Include signatures on cards."
The signatures will no longer appear on the cards on the page and they will not be included on the printed cards.
Note: If you see someone attributed on a card signature who you know didn't make that card, then this is how that happens. Someone, who you invited, shared their invitation with someone else. Each person gets a unique URL link in their invitation, so if someone else uses it to add a card, our system thinks that it is the person who was invited and attributes the card to them.
