In Adding Contacts, we just discussed how to add a brand new user, here in this section, we will discuss how to add a user who already has an iTWOcx account.
Just like adding an already existed company, there are two situations for an existing user: they exist on the project you are working on or they exist on other iTWO project.
1. Add a user which is already on the project you are working on.
Under this circumstance, the system will remind you that the account in current project and can not be added twice, click Close and enter a new account.
2. Add a user which exists on other projects of iTWO account.
If you enter an existing account, you will be presented with the following message, you can click Close to add a different one, or click Use This User to continue.
By clicking Use This User, that user's information will be added to the corresponding company.
A user can belong to different companies on different projects.
3. Synchronize with the template projects.
Like adding a company, a user can also be added to multiple projects that share the same template.
a. Access the user adding page. Enter the basic information, and tick the box on the bottom.
b. Click Save.
The company the newly added user belongs to should exist in both the template and child projects, or you can not synchronize that user to the child-projects.
c. Click Save.
d. Click Done.
Display email when importing users.
When you are importing users from the company details page, the details for the users will include, the users name, email address, whether they exist on the current project or not and their account status
