By becoming an RWA member, you have access to information not always readily available or not known. I was truly naive before I joined my RWA chapter. When the Writer's Market said send an outline of the story, I sent an outline. Yep, Roman number I, II, etc. I still blush to think about it.
Most chapters offer a variety of workshops from the basics of writing to promotional opportunities.
Take advantage of these workshops. Encouraging words for finishing a chapter may be enough to make someone continue on to the next chapter. Special tributes for a first sale make a wonderful time even more heartwarming. Attending someone's booksigning not only makes the author feel appreciated, but gives the attendee a chance to learn how its done. After all, you may be there someday, too.
