i dunno if there's a way to reply to guestbook comments, so i'll respond here where it's most visible:
the font i use is "OCR A Extended" which is one of the defualt fonts on my computer, so i have no idea how one would go about finding and downloading it unfortunately (i only ever use the fonts that are already in my computer)
on my stamps i did have to edit the "M"s to be more readable because of how small stamps are, but otherwise i didn't change anything else
