Hi: If you need to assign people to a project one at a time, then you would go to the project, Project Actions, Sharing, and add the individual(s) and grant them VIEW to the project. It will take a while to catch up, as you will have to grant access one project at a time, but when it's done, you'll have external customers able to see their projects and no others. We use the person's email as their login ID. We give them a standard password that they have to reset the first time they log in to see their projects. They all have their own Review license, which shouldn't cost you anything if you have the Collaboration package. Another way would be to give them a scheduled report of their project information – they wouldn't have to log in at all, unless they want to. You could send the report to each external individual who needs to view things on the project. If you send them scheduled reports, you don't need to create IDs for them, you just add their email address to the Send to: list for the report. Does that help? Eric
