[otrs] anyone is allowed to edit the survey but no trace is left

Hello there, One of our customers told us everyone was able to change the survey. When we went and tried we realized he was right: any user who can click on the survey, can also edit it and what is worse, all changes appeared to be created by the user with ID 1. We opened a bug report for that: http://bugs.otrs.org/show_bug.cgi?id=7715 Are you guys experiencing the same? How can we avoid it? Thanks, Leonardo Certuche www.itconsultores.com.co Medellín, Colombia
