[otrs] Customer Ticket view

Hello there, i found one interesting thing. when customer create ticket and then agent close it with some coment. The customer may see only the status of his ticket, like closed, but no agent coment to it's zoom. The question is how to show to the customer full history with the agent comments? Thanks in advance. -- IMPORTANT NOTICE: This email is confidential, may be legally privileged, and is for the intended recipient only.
