You'll find three short videos here: http://eslreading.org/teaching/esl/readibility.html  The first shows an excellent new free tool which you can easily install in your brower to make web pages easier to read and print.

I prepared to the other two presentations: one on using grammar check and the other on readability stats in MS Word. There's also a page on layout & vocabulary here: http://eslreading.org/teaching/readability/layout.html
