How do I Increase the intensity of the vibration on the samsung captivate.?

I just got the Samsung Captivate today, and Have started get it customized and get it ready for use. I found out the way to make it vibrate when a message come in, but its barley even a pulse. Is there a way to increase the intensity of the vibration on text messaging? I know there is a way to increase calling vibration, but that does not affect text messaging thanks.How do I Increase the intensity of the vibration on the samsung captivate.?Settings%26gt;Sound and Display%26gt;Vibration Feedback
