It's Vegas- "Audio Topics" as opposed to Vegas- "Video topics". They did this almost 8 months ago, when there was only one "Vegas" forum and audio users where complaining they had to weed through all the Video topics, to find an audio topic and vice-versa. This split of forums happened just after "Vegas Video 3.0" was first released. So don't get your hopes up too much with your sceptacism.
Yeah, I know Red - it was a joke (light relief). I was one of those aggitating for the split to be (re)made. The topic list is a start. Next, the app !
