After feeling dumb for not being able to figure out how to transfer stuff with a direct cable connection, I did manage to get some programming stuff done. There is now a feed for the Weekend Edition Sunday Puzzle, wesun_puzzle. And, if I did everything correctly, it should automatically update itself on Sunday evenings.
I notice that they don't have a new one posted for this weekend. I imagine they were talking about Columbia all weekend, so didn't do a puzzle.
