I was hoping to have the notification bell alone that would show site wide (not just in the forums) and I got it to show but the slider doesn't show properly (hides under the nav when in the header).
Any other way to get it to work? Or either a page I could link to (so I could set a custom icon) or another notification system? I'd love to have one that I could add other messages/notifications to (forum posts, broadcasts, comments on their posts, etc). Just curious if you have a way to do this or know of something that integrates well to do this.
Use the "My Profile and Notifications" Widget. You can put the widget on regular sidebars or on the wpForo sidebar.
You can find wpForo widgets in Dashboard > Appearance > Widgets admin page.
This widget is very flexible. All components can be disabled. For guests this widget displays [login] and [registration] buttons with different widget title. You can change widget titles too. Also, you can fully disable this widget for guests and keep it only for logged-in users.
