This really isn’t a InstaDMG issue but wanted to ask the ? here

Hello all. To start with I'm sad to see that instadmg might not be further developed with the developer leaving for greener pastures. The couple weeks I've been playing with it, I'm really liking what it can do. On with the question. I've created a 'standard' image with a couple add on applications like fire fox and VLC with no problems. The next thing I'd like to do is have some standard (for our business) machine settings added also to the image. For example, after 29 minutes the screen saver will kick in and one minute later it requires a password to unlock the system. I've been playing with Workgroup Manager from the developer pack and I've figured out how to make these changes to the computer that it is installed on but I'm not sure how to take that setting to another computer. So, would somebody be willing to do a little bit of hand holding on these two speed bumps with me? 1. How to save a preference, in this case the screen saver timer, so that it can be 'moved' to another computer. 2. How to incorporate question #1 into the instadmg image. Thank you from the imaging newbie. Mark
