That is not true. Users are added to the group at that specified value not after it. That leads to problem one.Minimum value:
Users will be added to this group if they exceedthe minimum value.
1) I have 2 restricted access groups, one requiring post moderation and the other suspending posting (read only access) among other privilege loses (temporarily of course). I want to have users added to the moderation at 2 warnings and removed at 3 because they are added to the posting suspended at 3. I can't do that because the max value at which a user is removed is after the specified value. So I would have to have the min and max the same but it won't let me do that so I had to set separate conditions in order to implement this.
2) I have a banned group used by the ban hammer extension so a user is shown publicly as banned. I also have autoban and I would like to set auto groups to move to the banned group when they reach that warning level however I can't because it is removing banned members that don't have any or enough warnings. There is an exempt group option but the plugin won't allow me to set the destination group as an exempt group. Why? The only work around that I can think of would be to have 2 banned groups and I shouldn't have to do that.
3) Notification upon removal doesn't always work.
4) Pre-defined groups can't be selected.
It's a nice plugin otherwise you just have to be careful with it.
