I've used the Google form for both self- and peer-assessment rubrics (no more sheets of paper to enter manually!). And we've posted links on bulletin boards to collect data from the school community. I'm also working on admin using a central Google Doc for our daily information (who's away with what sport when, etc) to cut down on emails and such.
A central Google Doc for daily announcements, schedules, etc, is long passed due. If your school has a TV studio, you could even link to the moderator in charge or to the student members of the production team. They can then pull directly from the site for prepping broadcast announcements.
