I wasn't on the site last year, so just wondering if your Mysterious Melody partner resets every day or something? I signed up yesterday and had a partner and today I don't, and have had to sign up for it again. =/

Yeah, you have a different person every day that you sign up for it.

Thank you! For some reason I thought it was the same person for the whole thing. :D

Nah, it changes every day. I think it's so that someone who gets a bad mm won't be stuck with them for an entire month.
