Anything you can do in the server launchers you can do in a batch file, just FYI. It's just a matter of finding the right command. I've covered everything listed on the DSmanager program in my text file (and many more it doesn't let you change). I haven't had time to go over the other ones to make sure there were any there I missed...

I agree though, there are certain things I wish you were able to change or had been added...
Then again, how many FPS games let you change the default respawn time? Then again, most FPS games don't HAVE a delay for respawns... ;)
