+### `setUserVIPStatus()`
+
+Requests that a user be considered VIP, or releases that request.
+VIP users are able to enqueue media while enqueuing is [restricted to staff or to users who know a password](./jungletv_queue.md#enqueuingpermission), and optionally have special roles associated with them in chat.
+
+Multiple applications may request that the same user be considered VIP, possibly with different appearances.
+In such cases, the most recently requested and not-yet-released appearance will be considered, and a user will not cease to be considered VIP until all applications have released their requests regarding that user.
+The resulting set of VIP users corresponds to the union of the requests made by all running JAF applications, plus the set of users manually defined on-demand by JungleTV staff.
+
+Applications do not have control over the entire set of VIP users, they can only affect the requests made by themselves.
+Requests are automatically released when the application terminates.
+
+#### Syntax

+  - `"vip"` - The user will appear as a "VIP User" with a crown or similar icon next to their name in chat.
