You can either post your novel or just part of it in this forum, or you can make a thread with a link if you're posting it someplace else.
Some things to remember if you want people to read your novel:
Use the default alignment, font size, and color when posting.
Double-space your paragraphs if possible.
Since this is just a rough draft errors are to be expected, but not so many that your story is unreadable. Capitalize, use spellcheck, etc. The basic stuff.
Unless your chapters are super-short, try to keep it to one chapter per post. If your chapters are really long, you may want to break them up into two or three posts.
In your first post, specify if you want comments/critiques or not.
If you don't want people to read your story but you still want to post it for whatever reason (to have a backup copy, to have a friend read it, whatever) make sure to specify that in the title of your thread or the first post!
