As it is with dodgeball teams, so too is it with Tango Workspaces: you need an invitation to join someone else’s.
If your team is on a Starter plan, anyone in the Workspace can add you, as long as they haven’t hit the 25 user limit.
If the Workspace has been upgraded to Pro, you’ll need to have the account admin invite you to the Workspace.
To make things simple when you ask, here’s a Tango on how to add someone else to a Workspace:
1. Go to Your Workspace homepage.
2. Click on Your Workspace…

3. Click on Workspace Settings

4. Click on Members

5. Click on "Invite Members"
You can also see who you've already invited on this screen under Invites.

6. Type the email address of the user you'd like to invite

7. Click on Send Invite

8. You'll see a pop-up when the invite has successfully been sent

9. You can also invite users by clicking on Invite Members on the bottom left of your screen

10. Type the email address of the user you want to invite.

11. Click on " Send Invite"
