Now, there's a way! YourOfficeMap allows you to find anyone or anything in your organization. You can search by name or thing; you can hover over an object to find out who or what it is.
If this has been set up for you by your administrator, just choose the login button to begin.
To be an administrator, all you need to do is register. Then you can upload as many diagrams as you like of your floor plans or maps or whatever.
