It is worth noting early that starter plans are locked into only 1 user (administrator) and can not invite team members.
- Navigate to the settings page by either clicking the left side panel or your avatar in the top left and clicking "Settings".
- You should land right were you need to be!
- Click the "Add Member" Button and enter a name and email and invite that user.
- This user will now be invited via email and will have to follow those instructions.
- You can control this member's portal permissions here as well!
