Each library has one account to access RT. Under this account staff are able to see all the tickets associated with their library. Not sure what the username and password is for your library’s account? Contact Co-op Support to find out.
You can login on the RT website https://support.libraries.coop/rt/
The Self Service home page displays current tickets submitted by email or in RT. To re-open a closed ticket simply add a new reply. This will change the status to open and alert Co-op Support that more attention is required.
