Holly Lisle is one of my favorite online writing instructors. She has written numerous novels and books on the craft of writing in different genres. She offers some free courses and some that are not free. Her website has downloadable worksheets to go with her books on the craft of writing.
Her most recent post is “Getting a Kickstart on Publishing.” Her sidebar has a list of other articles she has written. One that grabbed my attention is called “Chapter or Scene?”.
