If you are on the scene of an emergency and need help, point to one specific person and say “You, call 911″ (or whatever the number is for emergencies where you are). This gets the invidual involved in a personal way where saying “someone call 911″ will not. – Waldo Weyeris
A cool tool is anything useful that is superior to comparable items. If you think this tool is inferior suggest a better one. You are welcome to insult a tool, but comments containing insults to individual people will be deleted. Corrections of fact are always welcomed, if stated politely. Recommendations of better tools are dearly wanted and may be elevated to the front page.
