- an online noticeboard. When I was at uni, notices relevant to my group of students were either emailed out to everyone or uploaded as a word document to a shared drive. The former flooded my inbox with irrelevant notices, the latter was a pain to have to keep checking. Instead, I can imagine an online noticeboard with tags/directories and expiration dates set by the authors. Users would get a ping when a new notice went up for the tags/directories they had subscribed to.
