I am just using the standard NodeBB forum features, no crazy plugins that are meant to affect the notifications. The switch does not work, and digests are going out...
@tfraley@yariplus In my case I have a new and not very active forum, so I don't visit it daily. If a spammer registers and posts something a notification would be fine.
You could make a custom icon just by making a new class in the css file something like
.icon-topcoder {
background-image: url("http://cdn5.iconfinder.com/data/icons/Symbolicons_Transportation/24/Car.png");
background-position: center center;
width: whatever maybe 16px or 32px
height: same as what you put above
}
