David64 recommended a site to me which has usability info and plenty of other things going on there. It also has a competition to win a collection of books about website usability. The closing date is 31st July 2009 - and I didn't see anything about it being restricted to people in any particular country.
The details are here if you want to have a go:
Win A Usability Library!
(I have no relationship with that site.)
