I have a question as this is the first SS that I have participated in on this site. When I send the gift, do I put a card in revealing who I am or does it remain a secret? I've participated in others that do it both ways. Just wondering.

Secret secret secret!!

Some also use the address of the recipient as the "return address" so they don't reveal the secret in the return address...

It remains a secret.
I know most try to guess... but the fun of the secret (to me) is not knowing, yet receiving a wonderful gift intended just for you.
