This is excellent? Did you write all of this and put it together yourself Nicky? I shall definitely refer people to this site in future – no point in re-inventing the wheel!
Thanks for sharing.
Nicky,
Well done! This is just what academics and students need. The question and answer format, designed specifically for your users’ needs, makes it much more accessible than other , more technical sources.
It will help me a lot too!
