Tags and Categories are the two fundamental ways to organize content published within your Kidblog class. Tags and categories are similar, but have some important differences. The most important difference is that tags are student-defined and categories are teacher-defined.
Tags are author-defined labels assigned to a post. A user can create tags when editing a post. When entering a tag name in the Tags box, if a similar tag already exists in this Kidblog class, it will pop up. This "suggested tag" feature helps prevent spelling mistakes so the same label gets applied to posts.
Teachers can edit or delete tags via the "Tags" section of the post editor.
Because tags are user-defined, they represent more free-form organization of content by individual students. Users might label posts with keywords like "animals" or "good books". The Tags Widget will allow readers to find and filter content by tag name. The list of tags can grow large if users are using many different tags for their posts.
Categories are different from tags because students cannot define their own categories. If a teacher wants broad, pre-defined "folders" for types of posts, then categories are a good choice.
Teachers can create or delete categories via Settings->Categories for a class. Note that deleting a category does not delete posts, just the label.
You might use categories for broad subjects like "Math" or "Book Clubs." You can also use categories for students in small groups like "Blue Group" or "Lego Team 5". Categories would allow those students to easily filter posts to find other members of their group. Posts can belong to more than one category.
Both Tags and Categories sidebar widgets can be managed via the Settings->Themes/Sidebar for the class.
