While we're always tinkering with it, it's becoming past time for us to do some revamping of the help documentation: <a href="http://help.roll20.net/" rel="nofollow">http://help.roll20.net/</a>
If there's anything that needs to be added, corrected, or expanded upon, let us know.
That said, PLEASE, do not use this thread to: suggest features, highlight bugs, or request help without looking at documentation. The more effective you are in helping us to find what elements we need to make better, the more effective we'll be in implementing documentation for the entire community!
