Add team members to a team project or a team
If you're not yet an administrator, get added as a team administrator. Only administrators can add members to a team or team project.
On the TFS home page, choose your team or team project. If you don't see your team project listed, use Browse all to select it.
Manage members from the team home page.
Add individual Windows user account or a group.
You must enter user and group names one at a time. However, after entering a name, the account is added to the list, and you can type another name in the Identities text box before choosing to save your changes.
To verify that you've added all accounts, return to the home page and view the list of team members.
Send the URL to your team project (for example, http://fabrikamprime:8080/tfs/DefaultCollection/Fabrikam%20Fiber%20Website) to the new team members so that they can start contributing to the team project.
Team members inherit the permissions afforded to members of the team project Contributors group. Members of this group can add and modify source code, create and delete test runs, and create and modify work items. They can collaborate with other team members and check in work to the team's code base.
