You can add as many users as you want for a project. Browsee does not charge you for adding extra people to your project.
- Type the emails for users separated by comma and then click "Send Invite" to add them in the project
- If you have added a new user (having no accounts in Browsee), they will recieve an email to accept the invite and create a new account. As soon as, they will create an account, they will be able to see the see and edit the project.
