hi people

i am quite new to Linux and i have just recently had a problem where i cannot run sudo commands and the and remove app has gone from the applications menu. i think somehow my user privileges are corrupt. if i try to access uses and groups and go the unlock button it says cannot authenticate. when i try to use a sudo command, after entering my password it says "user is not in the sudoers file. This incident will be reported."

any help would be much appreciated it is quite irritating.
