Whoever I give my letter to, it's gonna have a more recent timestamp on it since I bought it the other day from the shop, compared to the one I will get from you or whoever can give me one with an earlier date on it so it'll be between the yellow letter and popcicle. Like I said, that particular info is on the first post of this thread.
So, whoever gives me theirs must also be okay with that their letter being in a more recent slot (aka towards the top left, depending on when the timestamps for the other ones you currently have are). Worst case, I am okay with it being after the beach ones since I can always hide them. Not ideal, but I can live with it.
When the letter is sent to me, please don't include a note with it. I won't include one in the one I send.
