A related question. Is there some sane way to tell which rules were touched 1-2 days ago? I see an option for modified up to 24 hours ago but then it goes "24+" which isn't helpful for me. I know I can hover over each of the many many rules and get that info but it's not ever going to be a priority for me to spend that much time. 
Since fiddling with rules yesterday I'm getting "Solarwinds SEM Alert!" email with "null at null" as the entire body.
I find that'd be the Default mail template (more than likely).
I look at historic data for that time and simply find an entry that an email was sent. Nothing terribly useful in the details.
I'm guessing I added email to a rule I touched yesterday that shouldn't have email.
Anyway, any help/tips would be appreciated!
