I need help with Server Signs ;(

In the description from Server Sign is:
Main Features:

• No limit: Unlimited commands per ServerSign
• Multi-role: Assign a variety of actions whenever a sign is clicked (even define different commands for right/left clicks)
  • Messages: Send messages to the player
  • Broadcasts: Send messages to the whole server
  • Player commands: Executes commands as if the player typed it in chat
  • Server commands: Executes commands as if it was executed from the server console
• Delayed actions: Any action can be delayed (from seconds to months)
• Looped actions: Any ServerSign can be converted to loop server commands with defined intervals
• Require permissions: ServerSigns can be set up to require permissions to use
• Grant permissions: Grants players temporar
• and so on...

And the point Server Commands: Executes.... want i use to execute commands that the players don't may!
But i can't find any description in the wiki ... to do that.
Can you please answer me what i must do , to use this function?!?
Thanks
