My client never received a notification to review my project, can they still review it somehow?

If your client does not receive a notification to review a project you submitted to them, they can still leave feedback. To do so, they can log into their ProZ.com account that is associated with their Blue Board record, and leave you feedback in their Outsourcer Control Center located here:
