# Mention Users or Roles in a Comment

Contentstack makes collaboration more efficient by allowing you to tag specific users or roles directly in comments. This feature ensures that the right people are notified via email and [in-app notifications](/docs/headless-cms/manage-notifications), streamlining communication and task management within your team. Whether you are seeking feedback, assigning tasks, or sharing updates, tagging simplifies the process of involving the relevant individuals or groups.

**Note:** You can mention a maximum of **20 users** (e.g., John Smith) and **20 roles** (e.g., Developer) in a single comment.

To tag a user or role in a comment, log in to your [Contentstack account](https://www.contentstack.com/login) and perform the following steps:

1.  Go to your [stack](/docs/headless-cms/about-stack) and open an existing entry.
2.  Open an entry and click the “Add comment” icon for a field.
3.  To tag someone in the comment, type “@” and type their name or role. Then, select the user or role from the suggestions. ![Tagging a user or role in Contentstack comments](https://images.contentstack.io/v3/assets/blt2d43f51baca745a8/blt5d5a272a9a301e5f/6788e1e05b4b8a822e68a935/Mention-Users-or-Roles-in-a-Comment-1-Tag-User-In-Comment.png "Tagging a user or role")
    
    **Note:** You can tag users or roles in [JSON RTE comments](/docs/headless-cms/json-rte-comments#tag-users-or-roles-within-a-json-rte-comment) for specific content blocks, text, and images.
    
4.  Click **Post** to comment.

**Note:**

*   Users or roles with “read” access to a content type or entry can use the comments feature.
*   You cannot tag external users or teams in a comment. In other words, you can tag or notify only users with access to the content type or entry within the comments.
