# Manage Collaborator Access

Use the Send Invitation option to manage collaborator permissions. You can review the list of collaborators, change the access level for a project, or revoke access to a run or project.

1. Select the shared project or run.
2. Select Share, and then select Send Invitation.
3. In the Collaborator Settings section of the Share dialog, change or revoke collaborator access.
4. Select Save Settings.

{% hint style="info" %}
The collaborator list uses the email address of the personal account or workgroup owner. Because users can accept shares on behalf of workgroups, the listed collaborator might not be the same as the user who received the invitation to share.
{% endhint %}

{% hint style="info" %}
Runs and projects have separate permissions. When you change access to a project, access to shared runs is not automatically changed.
{% endhint %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://help.basespace.illumina.com/collaborate/share-with-collaborators/manage-collaborator-access.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
