Control your own email accounts with this lesson from DiscoverCPanel.com.
We just found this great site about CPanel, and have obtained the first video in a series dedicated to helping you with your webhosting.
In Video #1, Webmail, CPanel Experts Bob The Teacher and Chris Morris show you how to control your own email accounts. (There is an option to purchase more videos if you like or just stick to the free one.)
Thought you'd be able to use this for your websites, too.
