Switching between the shoutbox and the tracker

By default, you'll have the Shoutbox (SB) showing up in all threads. But if you open any thread and click "Trackers" you'll have them show up in all threads from that point on. It depends on what you like. Some like to have the SB, others, the tracker. The image below will give you an idea.



You can also have the SB in a floating window by clicking "Float" in the panel at the bottom of the SB.

Note: Not all threads show up in the tracker. The LTE, for example, does not show up in the tracker. Neither do threads started in member forums. This has been done to prevent the tracker being swamped by threads of seemingly less importance and allow other threads a chance to be noticed.
You can even turn them off. In the Options page, expand Account Information and select "Hide Trackers and Shoutbox".
