Fixed Members get 50 Alerts (Reminder Message)

I have hundreds of groups. Some members have joined 50 groups. If they do not visit group for some time they get a reminder message Alerts for every group.

So members get 50 reminder Alerts. They get angry about this.
Could you please set a limit so that they never get more than 3 reminder alerts per day?

What do you think?

Added the option to restrict that. Also I have make a bit improvement this way.

The option does not work. Members still get 50 alerts. Even if 'restrict reminders per day' is set to 3.
