I would like to trigger users to fill in 1 of our profile fields. My idea is to give specific users, based on profile settings, a notification by pop-up when they log-in for example. In my case it's to set attention on the profile settings, but you could use it for other referrals ofcourse. 

In our case it's the profile field question: Do you like to receive Community news by e-mail? 

In the past this question wasn't mandatory. I want to trigger the group again that says ‘NO’ to increase our newslettres userlist.
