Haven't used it. Just read the copy on the site. Seems like if you don't need the bells and whistles, you can get a free utility that sets screen resolution(perhaps by command line) and set up a .cmd file or shortcut with the proper settings and put that in the StartUp folder. When you log on, it will set the screen res. Just put one shortcut set to preference in each users StartUp folder.
edit: here's a link to one. Google should come up with quite a few. Also try SoftPedia.com. They have lots of free programs as well as the shareware.
Also NirCmd may do it. It's a free general-purpose command line tool that can do most anything from setting audio volume to window sizes to screen resolution: http://www.nirsoft.net/utils/nircmd.html
Here's an example screen mode setting command to set the display mode to 800x600x24bit colors nircmd.exe setdisplay 800 600 24
