Move of CVS/SVN to centre Ross 1/11/11 Done
Move of admin samba to centre Craig 1/11/11 Still on going

Mini projects are projects which need to be completed but which should not require sufficient effort to make them a full blown project.

Ones to consider:

  • Some form of local tiny.url service, perhaps
  • revisit CalDAV - dcspaul says things have come along and software is much better now.
  • When/if moving www.inf from cvs to svn publishing, look at RT 60294 to see if we could cater for some why for publishers to say "put this is svn, but don't publish on web".
  • RT 59215 - request to add Forum print queues to webprint.inf, ie not just AT pcounter queues.
