Subforum dots

[Ashley1]

Depends what you want to change them with. They are sprite images taken from

.subforumicon {
height: 10px;
width: 10px;
display: inline-block;
margin: 0 5px;
background: url(images/mini_status_sprite.png) no-repeat 0 0;
}

Here is a tutorial that will help you replace those images with Font Awesome CSS:
