Is there any where on the web I can learn how to run a hosting business and how to use the Webhost Manager and CPanel
getting my first dedicated server this week after being a reseller for two years...The present webhost manager manual isnt to good at discribing how to use the features.

This would probably be the best place to start :)

Any day now there is going to be a step by step tutorial on it...
sheesh.
Webhostingtalk.com is probably the largest knowledge base on web hosting out there. You have about 247,720 posts ahead of you to read and your getting your dedicated server in the week, so I recommend you get cracking :).

Yeah, I think you're coming to the right place! Jump into the "Running a web hosting business" and "Dedicated server" forums and you should get many invaluable resources there.
