I just found another good blog (it's getting cozy in My Blog Cabin at the right) that is loaded with some good tips.
They're a bunch of authors called the Deadline Dames, and their blog is http://www.deadlinedames.com/. Today's post is particularly good. It's five tips for writers just starting out, so check it out.
You can also follow them on Twitter at http://www.twitter.com/DeadlineDames.
