All new AGOL users are either given the role of Viewer or User depending on the original access request email sent by the users supervisor.
If a user wishes to change to a Publisher role that user and their supervisor should review the Publishing Polices for information on training requirements, cost, and standards. The supervisors should then send a Role Change Request email TRecs Location Information Services to request the role change to AGOL. Include a short explanation of the reason for the request and user name receiving the role change. Once the user is giving the Publisher role they should abide by the training requirement and standards of TRecs Location Information Services.
