This isn't a forum for promoting books so much as talking and learning and teaching and answering questions about all things writing. (Although you can put a link to your published book in your sig, and also list it in the AW library.)
People talk about writing here, and they form connections, trade tips, get feedback after they've been here a while, swap beta-reads, and face the squirrels in Share Your Work (password:vista). And kick around wasting time if they're feeling a bit knackered by the process. There's a huge amount of advice and experience to learn from for people who are self-publishing, and huge amount of info and advice for people who are trade-publishing or hunting for agents.
It is a big site, and little unwieldy (I say that with love, guys.) There's one rule - Respect Your Fellow Writer.
Take your time. We'll be here when you surface. (Not me and Maryn necessarily because timezones, but someone will be around...)
ETA: Congrats on your soon-to-be finished!
