The password was sent to those participating in the secret santa thing and who wanted it. That means there is more then one person on that account so they can make a post about their secret santa.
If you are participating and would like to know something about your secret santa you can pm me and I'll give you the password for you to post.
Oh ok... thanks for explaining! I'm actually not doing secret santa because I missed the deadline of when we were supposed to get our addresses in, but I was just curious... thanks again!
