[otrs] How to change skin / theme for all agents and customer-user?

Hi, I want to know if there is a possibility to change the default skin / theme for all existin agents (users) and customer-users? The skin / theme has been modified and saved under a different name. Now I want to apply the skin / theme to all agents (users) and customer-users at once .... :) Mit freundlichen Grüßen / Kind regards Markus Moj Technik TimoCom Soft- und Hardware GmbH In der Steele 2 D-40599 Düsseldorf Tel: +49 211 88 26 80 14 Fax: +49 211 88 26 70 14 eMail: MMoj@TimoCom.com www.TimoCom.com Geschäftsführer: Jens Thiermann, Gunther Matzaitis Amtsgericht Düsseldorf, HRB 34489
