Maybe having them set to No as default would be better in case someone installed this and didn't do the settings right off the bat. I know when I installed it I had like a zillion IM windows open (I use Trillian) and was working on adding forums and threads on the site all at the same time.
Also, I use Andreas' auto-moderation hack for posts. Will this send notices for any posts that hack sends to moderation? I would like to have the option for that, if at all possible, unless it already does it. Then that would make this request kind a moot.
