Well... I wanted to keep it secret, so I'd rather do it in private. It's a high fantasy novel, and I'd love some constructive criticism from someone with more experience.
As Cogito pointed out to me, read the "New Member Guide", specifically the section about posting a WIP a few paragraphs down. You will need to critique at least a couple of works from others and have some more posts plus a little time before you are able to post in the Workshop section. He also advised to keep the WIP post fairly short, around a thousand words or less, that is hard for me to do, this post is about 75 words long already.
