Hi
I am in the process of putting together as complete a set of IELTS resources as I can find. I have been doing this for my own students, but I am now opening it up.
The resources are all completely free: some are my own and the rest are from the net. They can be accessed at
Dominic Cole's IELTS Blog
which is really just a convenient portal to my resources site
Dominic Cole's IELTS Resources
I should add both sites are constantly being updated.
