Now you can see in realtime without reloading the page, all new threads, posts, new user registrations, etc. from Car Audio Forum - CarAudio.com Spy.
Keep in mind that even though it might seem to hang for a little while, it's still showing everything in realtime.
This page is accessible from the navbar, under the "Community" tab, then "Spy" link.
Keep in mind you have to be logged in to the forum, to see new posts in The Thunderdome, since its a member-only forum.
