Wordcounter

This is a great tool and something I have found very useful for writing essays with a tight word limit.

The majority of my reports have been 1,500-2,000 words, which I usually find to be really tough to keep to. If I sport a paragraph that needs to be cut down, I usually copy it into word counter and play around with it until I am happy with it and then paste it back into my word document.
