Aspiring writers have a lot of help today. The problem is to choose the right one. Some of the offered writing software is useful, some is just expensive. I like Scrivener because it is free of gimmicks. It is not a plotting technique so much as tool to organize all kinds of writing activities. The Mac version has more features, but the Windows version has the basic functionality that makes it such a useful tool. To my fellow songwriters I warmly recommend MasterWriter which is much more than a rhyming dictionary. If you consider buying a writing software get some information about what's on the market at Screenwriter's Store. Then you may want to check the reviews at the creative writing software review site. While a writing software can make it easier for you to write, you definitely don't need any to become a good writer.
