The Science Exchange platform hides personal email addresses to protect your privacy. More importantly, information regarding project details and changes that is captured on the Science Exchange order page serves as an audit trail. Messages and uploaded files cannot be edited or removed by Requesters or Service Providers, unlike email correspondence. In the rare event of a dispute, Science Exchange uses the audit trail to advocate for our customers. For this reason, we strongly encourage that all written correspondence be captured on the order page.
With that said, please feel free to exchange phone numbers and set up a phone call with the service provider. After the call, please capture details of the conversation on the order page, such as changes in the project scope, statement of work, or deliverables, to maintain the audit trail.
