I have never spent a lot of time with JavaScript and recently I was introduced to jQuery; now I am trying to include it in more of my development in hopes I get better at it.   I would like to say thank you to Kevin Griffin for the introduction he gave at the Roanoke Code Camp 2010, he did a great job on grabbing my interest and convinced me to use jQuery more often.
