 The second step requests contact information for the individual or group responsible for fielding user questions regarding the ATBD (Figure 20). APT stores information from all published documents, which authors can retrieve and use in other documents. Therefore, authors have the option to search for existing contact information stored in APT and should use this information whenever possible instead of entering information manually. This ensures that information is consistent across all documents, which is an advantage of APT.
 
+Document reviewers should be added as a contact. However, their information will not be included on the document PDF. Select “Document Reviewer” under roles related to the document. A minimum of two reviewers are required.
