[otrs] Hide tickets that are waiting

Hi list! When i choose to set a ticket as "waiting" and give in a date, how do i manage this ticket to be hidden until the given date? Btw. Is there a english forum and/or tecnical-faq for otrs somewhere? -- Best regards Mikkel Robin Nielsen WorldWeb Interactive A/S Idyl 9A DK-6000 Kolding Tlf: +45 70 213 214 Fax: +45 70 213 215
