I'm here to learn how to manage my dedicated server myself.

Hi Tomas022 and welcome to Web Hosting Talk! :wavey:
A couple points of interest are the forum guidelines (http://www.webhostingtalk.com/rules.php) and this answer guide (http://www.webhostingtalk.com/showthread.php?t=585586).

Welcome to WHT!

Thanks, i feel already at home.

Hello tomas022, i am sure you will find answers to many questions already here on WHT; but if you have additional questions just post them in the forums and i am sure someone will be able to answer your specific questions.
Good luck and welcome to the WHT forum.
