I had been following reviews of rightwriter for a while and finally decided I needed it so I bought the full version. It was the best decision I have made in a long time and well worth the money. The first time I used it on an English paper it found 4 major errors. I read and reread that paper 100 times I think and never caught those. They would have meant a lower grade for certain and now I know not to make those mistakes again. I learned something and received a higher grade than I would have otherwise. Definately worth having.

I tried whitesmoke and rightwriter side by side and rightwriter found more errors. Neither were perfect but they sure make proofreading easier. I use rightwriter now before sending an email or posting to my blog, it has saved me from many stupid mistakes.
