# Managing Users in Projects
All users, in Ango Hub, belong to organizations, and have certain roles assigned to them.
Every user has two different role levels: an organization-level one and a project-level one.
This page is about project-level user roles. For organization-level user roles, and for more on organizations, check out the [Organizations](https://docs.imerit.net/core-concepts/organizations) page.
## Adding organization members to a project
Here's how you can add an existing organization member to your project:
1. Enter the project’s *Settings* tab
2. Enter the *Members* section
3. Click on the *Add Member from Org* button.
From the dialog that pops up, choose the member you wish to add, their role, and click on *OK*
Alternatively, to add users in bulk, enter the "From CSV" tab. Create a CSV file conforming to the sample shown in the "Sample CSV" section, drag and drop it into the upload box, and click on "Review". Review the users which will be added and then click on "Add".
## Adding non-organization members to a project
You may add users directly to your project, letting Ango Hub taking care of inviting them to the organization.
When you invite users to your project this way, they will automatically be added to your organization in the "member" role.
1. Enter the project's *Settings* tab.
2. Enter the *Members* section.
3. Click on the *Invite to Project* button.
From the dialog that appears, enter the emails of the users you wish to add, separated by commas. Then, pick the project role you wish to apply to the new users and click on *Invite*.

If you have a comma-separated list of emails, you may paste it into the *User Email* field to quickly add all emails.
{% endhint %}
Alternatively, to add users in bulk, enter the "From CSV" tab. Create a CSV file conforming to the sample shown in the "Sample CSV" section, drag and drop it into the upload box, and click on "Review". Review the users which will be added and then click on "Add".
## Project-level Roles
Project administrators can assign org members to one of three roles: labeler, reviewer, and manager.
### Labeler
A labeler can, in essence, only annotate data and open issues. Labelers can also view data related to their own performance within the project.
Labelers (or annotators) can access personalized versions of the following tabs:
* Overview
* Tasks
* Samples
* My Issues
The *Overview* shown to labelers is a simplified version of that shown to project administrators and reviewers, only containing data about the labeler’s own performance.
The *Issues* and *Tasks* tabs shown to labelers are also limited, only containing the issues and tasks the labeler logged in has created.
The following are the actions that labelers can perform in Ango Hub:
* Create labels
* Create, reply to, resolve, and delete issues on their own tasks
####
The following are the data that labelers can view in Ango Hub:
* Their own performance from the Overview tab
* Their own issues from the *My Issues* tab
* Their own tasks from the *Tasks* tab
* All samples created in the project from the *Samples* tab
* Project instructions, task attachment, and task info
### Reviewers
Reviewers are equal to *Labelers*, with the only difference being that they have access to the *Start Reviewing* button.
### Leads
Leads are given significantly more permissions than labelers in Ango Hub.
The following are the tabs that leads can access in the projects where they are assigned:
* Overview
* Performance
* Assets
* Tasks
* Samples
* Issues
The level of information leads can see in the above tabs is the same as project administrators.
####
The following are the actions that leads can take within the platform:
* Label
* Review
* Delete and add label tasks
* Set benchmarks
* Set samples
* Rate tasks
* Create, reply to, resolve, and delete issues
The following is the data viewable by leads:
* All labeling data of all project members
* All performance data of all project members
* All assets
* All tasks
* All samples
* All issues
The following is a sample of what a lead can see from the Overview tab:
### Managers
Project managers are equal to project owners: they can access everything project owners can, with no differences.
