This is a very useful link and I hope you get some good use from it. The Online Writing Lab (OWL) has a number of worksheets to help explain several aspects of writing and the English language.
Of particular use is the Grammar and Mechanics section in the right hand navigation. Let me know if you can't find what you're looking for on this site or from the many links on the CW site and I'll try and get some help sheets made up when I get chance. Thanks.
Thanks for this link. Even with all the books I've written, I am always distraught when I get my first edit back. After I've written it, obsessed over it, proofed it three or four times, etc, then some smarty pants comes along and fills my work with red pen. It hurts every single time.
It has become almost an obsession to see some actual pages without red pen on it at all! Call me a dreamer! LOL! Anyway, thanks.
