We use the registered Help Desk for a Work Order System for our Maintence Man.I have tweaked the language files and reply emails to be a Work Order system for our maintanence man. Instead of giving him a paper list, we use your system. I have uploaded the modified file here if you are interested in marketing as having a work order system as well: http://www.mediafire.com/?fhgcw1jkemy.
