Niromia has a system like this. Every week or so we publish a newspaper with updates about the server and information about current systems we are working on.
It works out really well for us because if players ask us a question usually we can just tell them about the Newspaper and they won't bother us anymore.
I could see this easily being a global thing. Each classic playerworld has a section and all otherplayerworlds have little paragraphs if the playerworld wants to enter something.
