You have to post a recipe to the recipe section. At the top of the page you will see "Main, BrewSpace, Recipes", etc. If you choose the right drink category, and post your recipe, it will show up.
The kicker is that it is not a "work in progress" - and must be a proven recipe that you have seen through from start to finish, and actually tastes good.
If you've got a secret recipe that you love and are dying to share, hook up the community! If you've got plans for a recipe that you want to tweak or 'blog' about as it ferments, post it to the Ingredients/Recipes section in the forums, not the Recipe Database.
