BI XI R2 Desktop Intelligence

How do you send a document to another user from within Desktop Intelligence? The Send To > Users option that used to be on the File list in previous versions is not there any more.

The help file section on 'sending document to users' is a description of how to use folders and categories but contains no instructions on how to send a document. The section on 'sending to groups of users' instructs you to click 'List' and then selec the group(s) you want, but there are no instructions as to how you get to the point of selecting List! There is a note underneath that says "This option is only available when you previously selected the Send To then Users on the File menu" but as there is no Send To option on the file list!
