I hope you created a second user, and am not running around as root doing everything. If you are, it is time to slow down, and start using a normal user account instead of the God account.
If you were to catch a bug, or malicious program, and you are running root, you can torpedo your box. One of the big features of Linux security is NOT to run normal programs as root.
IN the windows world, you almost always need to be a member of the Administrators group in order to do things. Not the case in Linux.
first thing i did was create an account so that im not the root user, i have to enter a password to change anything associated with that stuff.
