You're correct, it's when something is edited. Any time you change something about your user account, like a profile field, it will create that event. But I _think_ that it's any update to the user, not just manual ones, which can happen by ldap synch's and maybe even some other stuff that jive does.
If you want to not get those events, you can use this filter:
Thanks, Dirk. I already applied that NOT filter and it works. I won't include that data, as what I am creating are weekly versions of the User Adoption report from CMR.
