I may not make a frequent habit of shameless link-baiting but I have to in this instance. For the price of shipping you can upgrade your current Logos packages to the brand new "ND" packages. Take a gander: Free Upgrade from Logos Bible Software OC to ND at PhilGons.com.

Of course I've already postulated that ND must mean "Non-Disclosure" since I didn't see anything about this on the Logos site.

If you've already made up your mind you can just aim straight for the upgrade page.
