In order for clients to use this site, you must first add client users to the organization listed as the client for that project, if you have not already done so (see "Add Client Users"). Then add these client users to the project team by navigating to the project's home page and scrolling down to the last item, Project Site, under Details, and click on the "Details" link.

When the "Project Site" Page for that project appears, scroll down to the "Permitted Client Users" section, and click on the Add button. When the "Add Team Members" Page appears, click on the checkbox next to the name of the client user you want to add and click the Add button again.

The client user can now login to the client site but will not be able to add or edit items until you publish that user. To publish a client user, navigate to the Permitted Client Users Section of the Project Site Page. Click next to the name of the user to be published and click on the Publish button.
