Blog posts can be organized by categories. There is no limit to the number of categories you can create, and you can assign multiple categories to a blog post.
There are two ways to create a blog category.
First, from the menu click on Blog > Categories. From here you can add new categories by giving them a name and clicking the Add New Category button.
Delete a category by clicking theX next to a category name. Deleting a category has no affect on any blog posts assigned to the deleted category. The blog post will continue to be available in any other categories assigned, or, if no other categories have been assigned to a blog post will appear under the All category.
You can also create a new blog category when creating a new blog post. This is also where you would assign categories to your blog post.
