Attached is a Project Object based process that, at project create, will grant resources on a team (Resource OBS Level) Collaboration Manager to the Project. The Architecture for this solution uses GEL scripts that XOG the Resources onto the Project's Participants then grants them Collaboration Manager permissions - a fully supported and 'SaaS safe' solution for both On-Premise & On-Demand.
Unlike the Grant Administrator Collaboration Manager process, this will require some SQL knowledge for you to update the SQL to meet your organization's requirements.
MSSQL and Oracle version are in the zip. Oracle has not been tested. Please let me know your Oracle results - we can update the zip if necessary.
