O Week advice?

I've been asking people for O Week advice. What works? Waht doesn't? What's the best way to make contacts that actually stick? What's the waste of time?

A lot of people are still working hard with the cold-contact business of wandering around the campus and the queues of the Christian Union free BBQs and getting contact details for people interested in stuff.

But some other campuses seem to be a little less focussed on getting a mass of contact details, and more on advertising smart - with postcards sent to uni housing, nice looking fliers and a good public presence.

What's your advice?
