It's entirely possible that there are people out there that prefer to read through official user manuals for software products. If you're one of these people, go ahead and hit up the Connect support page for links to documentation galore (sidebar under Adobe Connect 8.0 Help).
If you're everybody else, then you may be interested in some great, free video-based training offered by Adobe. There are two ways to access this library of tutorials:
- Adobe TV - Learn Adobe Connect 8 channel - while you're here, check out the plethora of free Adobe-related training.
- Connectusers.com Getting Started with Adobe Connect 8 curriculum
The actual content is the same, but the videos are organized a bit better on Connectusers.com.
If you're into paid training, there's a great course on Lynda.com presented by (fellow Adobe colleague and friend) Tim Plumer Jr.
