I think we can probably simplify this component a little bit

```
<label ...>
  <input type="radio" ... />
  <i class="icon-oae-private" ...></i>
  <span> __MSG__PARTICIPANTS_ONLY__</span>
</label>
```

I think the aural text isn't adding anything here as there is already text showing, and the selected style can probably be done through CSS only.
