I think this is an awesome idea! And having it set up as a log is also excellent. Even if someone doesn't have a "submission" ready in advance, they can see the log, go "OH YEAH HAY" and... possibly make a post that's an article that their character submitted? Lord knows I'm bad at planning things well in advance, but I churn out good stuff on the spot.

There's also the advantage of people in posts going "Here's last month's paper. See page 3." and linking right to the log! Just like people link to Dist's letter and the other documents floating around.
