Katat Choi, a Monash Uni IT student, graciously offered up his time to help design a
website that more suited our needs. Katat has done an amazing job, we think it
looks and feels great. However even beyond the aesthetics and new features which
visitors see, are a range of Annual Report 2009 behind-the-scenes changes that will
make running the program much, much easier in 2010.
