Reception holds small bottles of water which are available for any lecturer or seminar host.  Please collect a bottle from them if you require water in your lecture.

It is usefully to periodically look at the 'Broken link's report, which will list any links on the site that have been broken.  In particular code 404: 'Not Found' errors are likely to be mistakes.  Others can be ignored, for instance links to Moodle at vle.cam.ac.uk always give an error.
