What MCX records do you change?

(1 of 2 related threads search identifier: creating default settings) So I figure a bunch of us are in environments without apple servers, but with enough apple machines that we are using instadmg AND have a need to set certain default settings that end-users cannot change. I use workgroup manager and a guest computer account to set some of these defaults (many of which I got from http://managingosx.wordpress.com/ the writer of which frequents these forums so, thank you!). I know that much of this can be done using dscl to write mcx records during the instadmg process, I just don't know enough of those commands to really make good use of them. I wanted to start this thread as a good place for people to note which MCX records they write OR which preferences they are managing with WorkGroup Manager so that all of us can learn. So far, I use mostly the basics already built into WorkGroup Manager, as well as those I learned from the aforementioned website. I am researching fine-grain printer control and a few other things. I am hoping eventually to flip all these items to MCX record writes so I can do them one at a time instead of as a monolithic single install. What is everyone else doing?
