Find the user that you want to assign a directory to. Click on the 'directory' icon to the right of the user name.
This will show which (if any) directory listings they currently control.
To assign a new directory listing, click the 'Assign a microsite to the user link'. You will be presented with an explorer view of the IDmedia folders. Navigate to the folder which the business listing is in and then click on the business name to assign the user to that business.
The user is now assigned to the directory listing.
* Directory listings are level 1 by default, which shows minimal information. To change the level of the directory listing, see Upgrade Directory Listing.
