Sorry for the delay in getting the Quick-Start user guide finished. Had to iron out a few details. Note that the Navigation Menu on the right has been divided into two sections: Downloads and Other Resources. I felt it was necessary to split up the Navigation Menu like that. As LRO & its resources grow, this organization will become more useful. :-)
To download the User Guide, click on the link entitled "LRO Quick-Start Guide"
Even if you've explored LRO already, you might still benefit from the instructions in here. Especially if you have problems with Access giving you security warnings, there are detailed instructions on how to fix Access's security settings to work with LRO. A more detailed user guide will come later.
