Comment: I received the envelope quite late with no prior communication, even though it was marked sent on time. I reached out and was asked for proof of the postmarked date, saying this isn't like you. I noticed two other raters rating around the same time I received mine, i.e., 2-3 weeks late, and one who rated earlier but her message said she "assumed" one of the envies she received had been from you. I would have been happy to hear from you in advance if you couldn't make the swap date.
