**What is a Domain in “My Questions”?** 
A Domain is a skill name or category under which questions are organized. Domains can be grouped into folders or sub-folders for easier management. Each domain can contain multiple types of questions. When creating your own question, the relevant domain must be created first.

A **Domain Group** is a folder that contains multiple domains. Each Domain Group can also contain sub-folders — meaning Domain Groups can be nested inside other Domain Groups — allowing for a more structured and hierarchical organization of your question library.
