Replying to Anonymous NS secrets

Hey guys, I love posting on LM 'things you can't say'. However there are some things I'd love to voice that I don't because I don't want you guys knowing it's me.
postsecret.com as some of you may know is a blog set up by a guy who receives postcards with secrets on them, i love the idea.

So I'm wondering if we could get some section of a site or if there is any alternative where only people from here can post and see secrets. I don't mean you need to log in with a password or anything, I just think it'd be cool if there was a log of secrets we wanted to share with other ns'ers anonymously.

[TL;DR is there a site we can find where ns'ers can post secrets anonymously that only we can see?]
