This lady posted a thread on Metafilter with the following:

My grandmother passed away in 1996 of a fast-spreading cancer. She was non-communicative her last two weeks, but in that time, she left at least 20 index cards with scribbled letters on them. My cousins and I were between 8-10 years old at the time, and believed she was leaving us a code. We puzzled over them for a few months trying substitution ciphers, and didn't get anywhere.

My father found one of the cards the other day and I love puzzles and want to tackle the mystery again. Based on some of the repeating segments (many lines start with PST, many end with PAGA, and TYAGF repeats often at the end), I'm thinking they may be song lyrics. She inserts lots of backwards commas, and strange breaks at various points that could indicate stanzas. The back of the card has two numbered lines that contain the same letters.

Here is what the front of the card looks like.

Now, people that don't even know her are working on translating it, trying to figure out the message the dying woman was leaving. They figured out the back of the card was 'The Lord's Prayer". Based on the back, and some other clues , like people's initials, they are assuming the front is a personal prayer, and they are trying to figure out what it says. It's pretty amazing! It may not be exact, but I bet they are coming pretty close to the original intent.

I love it when a part of the internet works together to do a good thing!
