I tend to put sentences into google in order to verify that the structure / grammar / spelling of my writing has been used before. This makes writing longs posts very tedious and annoying, but I'm way to afraid to make any mistakes. Most of the time I end up deleting the whole post, just to be done with it. I wish there were more people like you who don't look down on people with poor english skills.

Anyhow, can anyone recommend a book or some articles on how to improve writing skills, especially of technical nature ?
