Very welcome.

As of now, I still get these emails, but there is no option for "Notify me when a comment is flagged." It's as if the behavior is there, but I don't have the ability to turn them off.

@[deleted]: Did you follow the instructions?  Because it is there for me.

I've attached a screenshot of my Notifications Preferences. Does yours look different? 

I tried something.  Can you log out of the forums, back in and then take a look at that screen please? (I'd love another screen shot of it)

@[deleted] thanks, now I have access to "Category Notifications" but still nothing about flagged comments (had to zoom out on the page to get full screenshot).

Okay one more try.  Log out and back in and see if it shows up.

@[deleted] thanks, it shows up now!

Yay!  I found the right setting. :)
