I have written an ASP application for room booking that some of you may find useful, called SiCS Lite.
http://www.ktdevelopments.co.uk
It is totally web based and supports 1 and 2 week timetables. Period lables can be changed to eg. lunch or break etc.
Users can delete their own bookings and view other people's.
User details can be bulk uploaded via a csv file.
A free (externally hosted) demo can be set up for schools to use for a month. There is also an online public demo to try out.
[i sincerely apologise that my previous post (before this edit, see post below from Dos_Box) did not make it clear that I was the author of this software]
