I am not sure i am getting the most from cpanel. I always use the file manager and the stats viewers, but little else except email. What tips can anyone suggest to return more value from this tool?
Hmm, the first thing that comes to mind, is that if you don't miss it, you don't need it. I don't know why you are looking for better use? Is it the price you paid for it?
CPanel is a great tool for a sysadmin and saves a lot of typing commands. On the other hand, it limits the freedom you have to do your own thing with the server. CPanel is mostly usefull, because you can delegate a lot of stuff to your customer or reseller.
By the way, I think the FileManager sucks for years already.
