Similar to the idea of the noticeboards, but delivered via mailboxes or available from a street vendor. I like the noticeboards but I don't know or remember where to find them, and chances are I'm quite a trek away from the nearest one.
It could include details of new regions/streets/projects from the devs, but players could also purchase space and write their own pieces about upcoming parties or new companies, provided they have the Penpersonship skill of course!
