For the stuff you work out before you start writing/sort of outside the writing, like world building, plotting, etc. The parent forum is public, so if you want to brainstorm the details of your work in a members-only space, use the Brainstorming subforum!
From narrative voice to tense, perspective, POV, motivation to beat writers' block, and more... whatever it takes to get the words out to build your story, discuss it here... or add inspirational resources like noveling soundtracks, prompts, and pictures!
Once the novel or story is written, there's still a lot of work to go. Discuss revisions, getting published, promoting, etc in this forum, or use a subforum to find a beta reader, request feedback, or promote your published work.
If you're participating (or thinking about participating!) in this year's NaNoWriMo, this is the place to go to find community with your fellow Worldsmyths and hammer out ideas! We'll have posts for word counts, excerpts, brainstorming, etc. This forum is members only.
