Start by visiting the Community section of the site. On the left hand side, you can view the most popular topics for discussion. Once you have a good sense of what's being discussed today, you can click "New Post" at the top of the left hand column to start a new discussion. As part of that process, you'll be asked to choose a topical community like "Home Cooking" or "Restaurants & Bars". Choose the best match for your discussion and add appropriate tags like locations or ingredients to help others find your post.
Picking a Community allows your readers to get a sense of the general area of the food world that your post is about. For instance, in addition to tagging your post with Fish it is important that you indicate to your readers whether you are talking about cooking fish at home (Home Cooking) or ordering fish at a restaurant (Restaurant & Bars).
If you are still not sure where to post, you can contact our moderators for guidance by clicking "Submit a Question" at the top of this page.
You can also comment on a specific Chowhound video, recipe, or article on the page where you view it.
